Treatment of the thiosemicarbazone 2‐FC6H4C(Me)=NN(H)C(=S)NHPh, a , with palladium(II) acetate in acetic acid, or with lithium tetrachloropalladate(II) in methanol, gave the tetranuclear cyclometallated complex [Pd{2‐FC6H3C(Me)=NN=C(S)NHPh}]4 (1a) . Reaction of 1a with the diphosphines Ph2P(CH2)2PPh2 (dppe), Ph2PCH=CHPPh2 (trans‐dpe) Ph2P(CH2)3Ph2 (dppp) or Ph2P(CH2)4Ph2 (dppb) in a 1:2 molar ratio gave the dinuclear cyclometallated complexes [(Pd{2‐FC6H3C(Me)=NN=C(S)NHPh})2(μ‐Ph2P(CH2)nPPh2)], (n = 2, 2a ; 3, 4a ; 4, 5a ) and [(Pd{2‐FC6H3C(Me)=NN=C(S)NHPh})2(μ‐Ph2PCH=CHPPh2)], ( 3a ). The X‐ray crystal structure of ligand a and of complex 2a are described. The structure of complex 2a shows the palladium atom is bonded to four different donor atoms: C, N, S and P. 相似文献

Mixed‐ligands hydride complexes [RuHCl(CO)(PPh3)2{P(OR)3}] ( 2 ) (R = Me, Et) were prepared by allowing [RuHCl(CO)(PPh3)3] ( 1 ) to react with an excess of phosphites P(OR)3 in refluxing benzene. Treatment of hydrides 2 first with triflic acid and next with an excess of hydrazine afforded hydrazine complexes [RuCl(CO)(κ1‐NH2NHR1)(PPh3)2{P(OR)3}]BPh4 ( 3 , 4 ) (R1 = H, CH3). Diethylcyanamide derivatives [RuCl(CO)(N≡CNEt2)(PPh3)2{P(OR)3}]BPh4 ( 5 ) were also prepared by reacting 2 first with HOTf and then with N≡CNEt2. The complexes were characterized spectroscopically and by X‐ray crystal structure determination of [RuHCl(CO)(PPh3)2{P(OEt)3}] ( 2b ). 相似文献

Reaction of tetraphosphine complex [Mo(κ4‐P4)(Ph2PCH2CH2PPh2)] (1; P4 = meso‐o‐C6H4‐(PPhCH2CH2PPh2)2) with E‐1,3‐pentadiene in toluene at 60 °C gave the η4‐diene complex [Mo(η4‐E‐1,3‐pentadiene)(κ4‐P4)] (2), which is present as a mixture of two isomers due to the orientation of the Me group in the diene ligand. Treatment of 1 with Z‐1,3‐pentadien also resulted in the formation of 2 as the sole product after heating the reaction mixture at 90 °C. Whereas the reaction of 1 with 1,3‐cyclohexadiene at 60 °C afforded the η4‐diene complex [Mo(η4‐cyclohexadiene)(κ4‐P4)] (6), that with cyclopentadiene led to the C‐H bond scission product [η5‐C5H5)MoH(κ3‐P4)] (7). Detailed structures were determined by X‐ray crystallography for 2, 6,and 7, and fluxional feature of 6 in solution was clarified based on the VT‐NMR studies. 相似文献

The coordination chemistry of platinum(II) with a series of thiosemicarbazones {R(H)C2=N3‐N2(H)‐C1(=S)‐N1H2, R = 2‐hydroxyphenyl, H2stsc; pyrrole, H2ptsc; phenyl, Hbtsc} is described. Reactions of trans‐PtCl2(PPh3)2 precursor with H2stsc (or H2ptsc) in 1 : 1 molar ratio in the presence of Et3N base yielded complexes, [Pt(η3‐ O, N3, S‐stsc)(PPh3)] ( 1 ) and [Pt(η3‐ N4, N3, S‐ptsc)(PPh3)] ( 2 ), respectively. Further, trans‐PtCl2(PPh3)2 and Hbtsc in 1 : 2 (M : L) molar ratio yielded a different compound, [Pt(η2‐ N3, S‐btsc)(η1‐S‐btsc)(PPh3)] ( 3 ). Complex 1 involved deprotonation of hydrazinic (‐N2H‐) and hydroxyl (‐OH) groups, and stsc2? is coordinating via O, N3, S donor atoms, while complex 2 involved deprotonation of hydrazinic (‐N2H‐) and ‐N4H groups and ptsc2? is probably coordinating via N4, N3, S donor atoms. Reaction of PdCl2(PPh3)2 with Hbtsc‐Me {C6H5(CH3)C2=N3‐N2(H)‐C1(=S)‐N1H2} yielded a cyclometallated complex [Pd(η3‐C, N3, S‐btsc‐Me)(PPh3)] ( 4 ). These complexes have been characterized with the help of analytical data, spectroscopic techniques {IR, NMR (1H, 31P), U.V} and single crystal X‐ray crystallography ( 1 , 3 and 4 ). The effects of substituents at C2 carbon of thiosemicarbazones on their dentacy and cyclometallation are emphasized. 相似文献

Treatment of Pd(PPh3)4 with 2‐bromo‐4‐methylpyridine, C5H3N(CH3)Br, in dichloromethane at ?20 °C causes the oxidative addition reaction to produce the palladium complex [Pd(PPh3)2 {η1‐C5H3N(CH3)}(Br)], 2 , by substituting two triphenylphosphine ligands. In a dichloromethane solution of complex 2 at room temperature for 3 h, it undergoes displacement of the triphenylphosphine ligand to form the dipalladium complex [Pd(PPh3)Br]2{μ,η2‐C5H3N(CH3)}2, 3 , in which the two 4‐methylpyridine ligands coordinated through carbon to one metal center and bridging the other metal through the nitrogen atom.

The o‐substituted hybrid phenylphosphines, PPh2(o‐C6H4NH2) and PPh2(o‐C6H4OH), could be deprotonated with LDA or n‐BuLi to yield PPh2(o‐C6H4NHLi) and PPh2(o‐C6H4OLi), respectively. When added to a solution of (η5‐C5H5)Fe(CO)2I at room temperature, these two lithiated reagents produce a chelated neutral complex 1 (η5‐C5H5)Fe(CO)[C(O)NH(o‐C6H4)PPh2‐C,P‐η2] for the former and mainly a zwitterionic complex 2 , (η5‐C5H5)Fe+(CO)2[PPh2(o‐C6H4O?)] for the latter. Complex 1 could easily be protonated and then decarbonylated to give 4 [(η5‐C5H5)Fe(CO){NH2(o‐C6H4)PPh2‐N,P‐η2}+]. Complexes 1 and 4‐I have been crystallographically characterized with X‐ray diffraction. 相似文献

Treatment of Pd(PPh3)4 with 5‐bromo‐pyrimidine [C4H3N2Br] in dichloromethane at ambient temperature cause the oxidative addition reaction to produce the palladium complex [Pd(PPh3)2(η1‐C4H3N2)(Br)], 1 , by substituting two triphenylphosphine ligands. In acetonitrile solution of 1 in refluxing temperature for 1 day, it do not undergo displacement of the triphenylphosphine ligand to form the dipalladium complex [Pd(PPh3)Br]2{μ,η2‐(η1‐C4H3N2)}2, or bromide ligand to form chelating pyrimidine complex [Pd(PPh3)2(η2‐C4H3N2)]Br. Complex 1 reacted with bidentate ligand, NH4S2CNC4H8, and tridentate ligand, KTp {Tp = tris(pyrazoyl‐1‐yl)borate}, to obtain the η2‐dithiocarbamate η1‐pyrimidine complex [Pd(PPh3)(η1‐C4H3N2)(η2‐S2CNC4H8)], 4 and η2‐Tp η1‐pyrimidine complex [Pd(PPh3)(η1‐C4H3N2)(η2‐Tp)], 5 , respectively.

Reaction Behaviour of Copper(I) and Copper(II) Salts Towards P(C6H4CH2NMe2‐2)3 ‐ the Solid‐State Structures of {[P(C6H4CH2NMe2‐2)3]CuOClO3}ClO4, {[P(C6H4CH2NMe2‐2)3]Cu}ClO4, [P(C6H4CH2NMe2‐2)3]CuONO2 and [P(C6H4CH2NMe2‐2)2(C6H4CH2NMe2H+NO3‐‐2)]CuONO2 The reaction behaviour of P(C6H4CH2NMe2‐2)3 ( 1 ) towards different copper(II) and copper(I) salts of the type CuX2 ( 2a : X = BF4, 2b : X = PF6, 2c : X = ClO4, 2d : X = NO3, 2e : X = Cl, 2f : X = Br, 13 : X = O2CMe) and CuX ( 5a : X = ClO4, 5b : X = NO3, 5c : X = Cl, 5d : X = Br) is discussed. Depending on X, the transition metal complexes [P(C6H4CH2NMe2‐2)3Cu]X2 ( 3a : X = BF4, 3b : X = PF6), {[P(C6H4CH2NMe2‐2)3]CuX}X ( 4 : X = ClO4, 11a : X = Cl, 11b : X = Br, 14 : X = O2CMe), {[P(C6H4CH2NMe2‐2)3]Cu}ClO4 ( 6 ), [P(C6H4CH2NMe2‐2)3]CuX ( 7a : X = Cl, 7b : X = Br, 10 : X = ONO2), [P(C6H4CH2NMe2‐2)2(C6H4CH2NMe2H+NO3‐‐2)]CuONO2 ( 9 ) and [P(C6H4CH2NMe2‐2)3]CuCl}CuCl2 ( 12 ) are accessible. While in 3a , 3b and 6 the phosphane 1 preferentially acts as tetrapodale ligand, in all other species only the phosphorus atom and two of the three C6H4CH2NMe2 side‐arms are datively‐bound to the appropriate copper ion. In solution a dynamic behaviour of the latter species is observed. Due to the coordination ability of X in 3a , 3b and 6 non‐coordinating anions X‐ are present. However, in 4 one of the two perchlorate ions forms a dative oxygen‐copper bond and the second perchlorate ion acts as counter ion to {[P(C6H4CH2NMe2‐2)3]CuOClO3}+. In 7 , 9 and 10 the fragments X (X = Cl, Br, ONO2) form a σ‐bond with the copper(I) ion. The acetate moiety in 14 acts as chelating ligand as it could be shown by IR‐spectroscopic studies. All newly synthesised cationic and neutral copper(I) and copper(II) complexes are representing stable species. Redox processes are involved in the formation of 9 and 12 by reacting 1 with 2 . The solid‐state structures of 4 , 6 , 9 and 10 are reported. In the latter complexes the copper(II) ( 4 ) or copper(I) ion ( 6 , 9 , 10 ) possesses the coordination number 4. This is achieved by the formation of a phosphorus‐ and two nitrogen‐copper‐ ( 4 , 9 , 10 ) or three ( 6 ) nitrogen‐copper dative bonds and a coordinating ( 4 ) or σ‐binding ( 9 , 10 ) ligand X. In 6 all three nitrogen and the phosphorus atoms are coordinatively bound to copper, while X acts as non‐coordinating counter‐ion. Based on this, the respective copper ion occupies a distorted tetrahedral coordination sphere. While in 4 and 10 a free, neutral Me2NCH2 side‐arm is present, which rapidly exchanges in solution with the coordinatively‐bound Me2NCH2 fragments, this unit is protonated in 10 . NO3‐ acts as counter ion to the CH2NMe2H+ moiety. In all structural characterized complexes 6‐membered boat‐like CuPNC3 cycles are present. 相似文献

Heterobimetallic Phosphanido-bridged Dinuclear Complexes - Syntheses of cis-rac-[(η-C5H4R)2Zr{μ-PH(2,4,6-iPr3C6H2)}2M(CO)4] (R?Me, M?Cr, Mo; R?H, M?Mo) The zirconocene bisphosphanido complexes [(η-C5H4R)2Zr{PH(2,4,6-iPr3C6H2)}2] (R?Me, H) react with [(NBD)M(CO)4] (NBD?norbornadiene, M?Cr, Mo) to give only one diastereomer of the phosphanido-bridged heterobimetallic dinuclear complexes cis-rac-[(η-C5H4R)2Zr{μ-PH(2,4,6-iPr3C6H2)}2M(CO)4] [R?Me, M?Cr ( 1 ), Mo ( 2 ); R?H, M?Mo ( 3 )]. However, no reaction was observed between [(η-C5H5)2Zr{PH(2,4,6-tBu3 C6H2)}2] and [Pt(PPh3)4]. 1—3 were characterised spectroscopically. For 1—3 , the presence of the racemic isomer was shown by NMR spectroscopy. No reaction was observed at room temperature for 3 and CS2, (NO)BF4, Me3NO or PH(2,4,6-Me3C6H2)2. With Et2AlH or PhC?CH decomposition of 3 was observed. 相似文献

Some new phosphoramidates were synthesized and characterized by 1H, 13C, 31P NMR, IR spectroscopy and elemental analysis. The structures of CF3C(O)N(H)P(O)[N(CH3)(CH2C6H5)]2 ( 1 ) and 4‐NO2‐C6H4N(H)P(O)[4‐CH3‐NC5H9]2 ( 6 ) were confirmed by X‐ray single crystal determination. Compound 1 forms a centrosymmetric dimer and compound 6 forms a polymeric zigzag chain, both via ‐N‐H…O=P‐ intermolecular hydrogen bonds. Also, weak C‐H…F and C‐H…O hydrogen bonds were observed in compounds 1 and 6 , respectively. 13C NMR spectra were used for study of 2J(P,C) and 3J(P,C) coupling constants that were showed in the molecules containing N(C2H5)2 and N(C2H5)(CH2C6H5) moieties, 2J(P,C)>3J(P,C). A contrast result was obtained for the compounds involving a five‐membered ring aliphatic amine group, NC4H8. 2J(P,C) for N(C2H5)2 moiety and in NC4H8 are nearly the same, but 3J(P, C) values are larger than those in molecules with a pyrrolidinyl ring. This comparison was done for compounds with six and seven‐membered ring amine groups. In compounds with formula XP(O)[N(CH2R)(CH2C6H5)]2, 2J(P,CH2)benzylic>2J(P,CH2)aliphatic, in an agreement with our previous study. 相似文献

Multinuclear solid‐state NMR studies of Cp*2Sc?R (Cp*=pentamethylcyclopentadienyl; R=Me, Ph, Et) and DFT calculations show that the Sc?Et complex contains a β‐CH agostic interaction. The static central transition 45Sc NMR spectra show that the quadrupolar coupling constants (Cq) follow the trend of Ph≈Me>Et, indicating that the Sc?R bond is different in Cp*2Sc?Et compared to the methyl and phenyl complexes. Analysis of the chemical shift tensor (CST) shows that the deshielding experienced by Cβ in Sc?CH2CH3 is related to coupling between the filled σC‐C orbital and the vacant orbital. 相似文献

The Reactivity of Dinuclear Platina‐β‐diketones with Phosphines: Diacetylplatinum(II) Complexes and Mononuclear Platina‐β‐diketones Addition of mono‐ and bidentate phosphines or of AsPh3 to the platina‐β‐diketone [Pt2{(COMe)2H}2(μ‐Cl)2] ( 1 ) followed by the addition of NaOMe at ?70 °C resulted in the formation of diacetyl platinum(II) complexes cis‐[Pt(COMe)2L2] (L = PPh3, 2a ; P(4‐FC6H4)3, 2b ; PPh2(4‐py), 2c ; PMePh2, 2d ; AsPh3, 2d ) and [Pt(COMe)2(L??L)] (L??L = dppe, 3b ; dppp, 3c ), respectively. The analogous reaction with dppm afforded the dinuclear complex cis‐[{Pt(COMe)2}2(μ‐dppm)2] ( 4 ) that reacted in boiling acetone yielding [Pt(COMe)2(dppm)] ( 3a ). The reactions 1 → 2 / 3 were found to proceed via thermally highly unstable cationic mononuclear platina‐β‐diketone intermediates [Pt{(COMe)2H}L2]+ and [Pt{(COMe)2H}(L??L)]+, respectively, that could be isolated as chlorides for L??L = dppe ( 5a ) and dppp ( 5b ). The reversibility of the deprotonation of type 5 complexes with NaOMe yielding type 3 complexes was shown by the protonation of the diacetyl complex 3b with HBF4 yielding the platina‐β‐diketone [Pt{(COMe)2H}(dppe)](BF4) ( 5c ). All compounds were fully characterized by means of NMR and IR spectroscopies, and microanalyses. X‐ray diffraction analysis was performed for the complex cis‐[Pt(COMe)2(PPh3)2]·H2O·CHCl3 ( 2a ·H2O·CHCl3). 相似文献

The reaction of the betain‐like compound O2C2(PPh3)2 ( 1 ) with [(cod)PtX2] in THF solution gives the salt‐like compounds (HC{PPh3}2)[(η3‐C8H11)PtX2] ( 3 , X = I; 4 , X = Cl) in about quantitative yields. The new η3‐bonded C8H11 ligand is the result of a proton transfer from the coordinated cod ligand to 1 with subsequent release of CO2. The X‐ray analysis of 3 shows the presence of two isomers in a 60:40 ratio, which differ in the bonding of the C8H11 ligand. 3 crystallizes in the triclinic space group with the unit cell dimensions a = 1091.7(1), b = 1141.5(1), c = 1649.4(2) pm; α = 80.34(1)°, β = 83.62(1)°, γ = 89.03(1)°, V = 2013.7(4)·106 pm3, Z = 2. 相似文献

Transition Metal Silyl Complexes, 44. — Preparation of the Binuclear Silyl Complexes (CO)3(R3Si)Fe(μ-PR′R′′)Pt(PPh3)2 by Oxidative Addition of (CO)3(R′R′′HP)Fe(H)SiR3 to (C2H4)Pt(PPh3)2 The complexes (CO)3(R′R′′HP)Fe(H)SiR3 ( 1 ) [PHR′R′′ = PHPh2, PH2Ph, PH2Cy; SiR3 = SiPh3, SiPh2Me, SiPhMe2, Si(OMe)3] react with Pt(C2H4)(PPh3)2 to give the dinuclear, silyl-substituted complexes (CO)3(R3Si)Fe(μ-PR′R′′)Pt(PPh3)2 ( 2 ) in high yields. Upon reaction of 2 (R = R′ R′′ = Ph) with CO, the PPh3 ligand at Pt being trans to the PPh2 bridge is exchanged, and (CO)3(Ph3Si)Fe(μ-PPh2)Pt(PPh3)CO ( 3 ) is formed. Complex 3 is characterized by an X-ray structure analysis. The rather short Fe — Si distance [233.9(2) pm] and the infrared spectrum of 3 indicate that the Fe — Pt bond is quite polar. 相似文献

Treatment of Pd(PPh3)4 with phenylchlorothionoformate, PhOC(S)Cl, in dichloromethane at ?20 °C produces the phenyloxythiocarbonyl complex [Pd(PPh3)2{η1‐C(S)OPh}(Cl)], 1 . The 31P{1H} NMR spectrum of 1 shows the dissociation of either the chloride or the triphenylphosphine ligand to form complex [Pd(PPh3)2(η2‐SCOPh)][Cl], 2 or the dipalladium complex [Pd(PPh3)Cl]2(μ,η2‐SCOPh)2, 3 . Continuous stirring of the dichloromethane solution of 1 at room temperature for 4 h forms the dipalladinum complex [Pd(PPh3)Cl]2(μ,η2‐SCOPh)2, 3 as the final product. Respective reactions of 1 and Et2NCS2Na or dppa {bis(diphenylphosphino)amine} gives complex [Pd(PPh3){η1‐C(S)OPh}(η2‐S2CNEt2)], 4 or [Pd(PPh3){η1‐C(S)OPh}(η2‐dppa)][Cl], 5 . Complex 1 is determined by single‐crystal X‐ray diffraction and crystallized in the monoclinic space group P21 with Z = 4. The cell dimensions of 1 are as follows: a = 9.5613(1) Å, b = 33.6732(3) Å, c = 12.2979(1) Å. 相似文献
