A reaction of CpFe(CO)2TePh with Re(CO)3(THF)2Cl in THF gave the heterometallic complex [CpFe(CO)2(μ-TePh)]2Re(CO)3Cl (I). Either iron atom in complex I is linked to rhenium by only one Phenyltellurolate bridge. When treated with (Dppe)Pt(TePh)2, complex I underwent transmetalation by elimination of two CpFe(CO)2TePh molecules followed by the formation of the heterometallic chelate complex (Dppe)Pt(μ-TePh)2Re(CO)3Cl (II). Complex II was also obtained in an independent way from (Dppe)Pt(TePh)2 and Re(CO)3(THF)2. Structures I and II (II · MePh and II · CDCl3) were identified by X-ray diffraction (CIF file, CCDC nos. 981467, 981468, and 981469, respectively). 相似文献

The isolation and characterization of two mononuclear complexes and one binuclear compound from the reaction between dicarbonyl(methylcyclopentadienyl) (tetrahydrofuran)manganese and 4-cyanopyridine are reported. The competition between the pyridine and nitrile nitrogen centers for coordination with the (η5 -C5H4CH3)Mn(CO)2 fragment results in the formation of two mononuclear complexes, of which the N1 -coordinated isomer is more stable. 相似文献

The products of magnesium oxidation with cyclopentadienyl(triphenylphosphine)nickel chloride were revealed. Effective equilibrium constants of adsorption of the reagents on the metal surface, entropy and enthalpy of these processes, rate constants, and activation energy were determined. A probable scheme of the process is assumed. 相似文献

Acetatobis(triphenylphosphine)dicarbonylrhenium (I), (PPh3)2(CO)2Re(O2CCH3), has been prepared in a novel way by treating (PPh3)2(CO)2Re(NHCOR) (R = C6H5, p-MeC6H4) with triethylamine and water in the presence of air. Oxidation of the ethyl group of the tertiary amine is presumably involved in the formation of the acetate ligand. Three-dimensional single-crystal X-ray diffraction analysis shows that the complex is octahedral with the phosphines in trans positions and the acetate ion acting as a chelating ligand. The complex crystallizes in theP21/c space group with cell dimensions a = 17.63(2), b = 9.72(1), c = 20.95(2)Å, β = 104°38'(6'), Z = 4. The mean values of bond lengths observed are Re-P 2.415, Re-O 2.21 and Re-(CO) 1.85Å. The same acetate derivative and a series of car?ylato complexes (PPh3)2(CO)2Re(O2CR') have been obtained from reactions of Re(CO)2(PPh3)3H with car?ylic acids R'COOH (R' = H, CH3, CH2Cl, CH2CH3, C6H5). When trifluoroacetic acid is used, a product of formula (PPh3)2(CO)3Re(OC(O)CF3) is isolated. The action of neutral ligands L on some of these products gave rise to derivatives of formula (PPh3)2(CO)2(L)Re(OC(O)R') (L = CO, R' = H, CH3, C6H5; L = pMeC6H4NC, R' = CH3), having monodentate car?ylato moieties. 相似文献

The ligands (HL1, HL2 and HL3) have been prepared and their reaction with fac-[ReX(CO)3(CH3CN)2] (X = Br, Cl) in chloroform gave the adducts [ReX(CO)3(HL)] (1a X = Cl, R = H; 1a′ X = Br, R = H; 1b X = Cl, R = CH3; 1b′ X = Br, R = CH3; 1c X = Cl, R = Ph; 1c′ X = Br, R = Ph) in good yield. All the compounds have been characterized by elemental analysis, mass spectrometry (FAB), IR and 1H NMR spectroscopic methods, and the structures of the ligands have been elucidated by X-ray diffraction. In the case of HL1, we have tried the reaction with [ReX(CO)5] (X = Br, Cl) in toluene and we proved the formation of the adduct also by this way by the isolation of single crystals of 1a′ · ½C7H8. 相似文献

Several palladacycle and platinacycle complexes have been prepared from easily available or naturally occurring indole derivatives, such as gramine and related compounds. Dimeric complexes were obtained with Pd(OAc)2, while Pt(DMSO)2Cl2 mainly afforded monomeric structures. A notable feature of these reactions was the formation of new M-C bonds between Pd or Pt and C-2 and C-3 of the indole ring. With ligands like 2-(2′-pyridyl)-1H-indoles, N-N metallacycles were generated instead: in fact new C-M bonds with the C-3 position could only form if N-substituted indoles were used. The reactivity of Pd dimeric complexes with PPh3, sym-collidine and DMAP was explored to obtain monomeric complexes. Three such compounds were prepared, one of which was characterized by X-ray diffraction. Metathetical reactions were carried out to effect a ligand exchange replacing OAc with halide ions, with the aim to synthesize μ-Cl and μ-Br bridged structures. Turning to the synthesis of hetaryl complexes, functionalization of the C-2 position on the indole ring was achieved. These complexes were prepared by substitution reactions starting from gramine and/or its alkylammonium salts. 相似文献
