2PCH2)2C5H2}Ru(C5H5) and {1,3-(But
2PCH2)2C5H2}Ru(C5Me5), respectively, with RuCl2(DMSO)4 in 2-methoxyethanol and characterized by 1H and 31P{1H} NMR spectroscopy, and X-ray diffraction. 相似文献

Photochemical properties of N-acyl-substituted aminomethyl- and 1-aminoethylcymantrenes were studied for the first time. These compounds form photochromic systems in solutions due to the intermolecular exchange of ligands at the manganese atom. 相似文献

The reaction of 5-IC5H4(CO)2Fe-1,5-C5H4Mn(CO)3 with Me3SiCCSiMe3 (2 : 1) in the presence of Pd(MeCN)2Cl2 afforded the I(CO)2Fe(C5H4—C5H4)Mn(CO)3 complex generated through migrations of the I atom from the Cp ring to the Fe atom and of the C5H4Mn(CO)3 group from the Fe atom to the Cp ring. 相似文献

Reaction of the cluster Os3(μ-CO)(CO)9(μ3-η1:η1:η2-Me3SiC2Me) with HC≡CCOOMe in benzene at 70 °C results in Os3(CO)9{μ3-η1:η1:η2:η2-C(SiMe3)C(Me)C(COOMe)CH× (5), Os3(CO)9{μ3-η1:η1:η2:η2-C(SiMe3)C(Me)C(H)C(COOMe)CH× (6), Os3(CO)9{μ-η1:η1:η4-C(SiMe3)C(Me)C(H)C(COOMe)CH× (7), and Os3(CO)δ{μ3-η1:η1:η4:η1-C(SiMe3)C(Me)C(H)C(COOMe)× complexes (8), containing an osmacyclopentadiene moiety. Complexes5–8 were characterized by1H NMR and IR spectroscopy. The structure of clusters5 and8 was confirmed by X-ray analysis. Complex7 is formed from cluster5 as a result of a new intramolecular rearrangement and complex8 is obtained by decarbonylation of compound6. Complex8 adds PPh3 to give Os3(CO)δ(PPh3){μ-η1:η1:η4-C(SiMe3)C(Me)C(H)C(COOMe)×. 相似文献

The reaction of Os3(μ-Cl)2(CO)10 (1) with Ph2PCH2PPh2 (dppm) in a toluene solution at 65°C results in novel osmium complexes [Os3(μ-Cl)2(CO)9]2(dppm) (2) and [Os3(μ-Cl)2(CO)8]2(dppm)2 (3). Compounds 2 and 3 were characterized by1H and31P NMR, and IR spectroscopy and their structures were established by X-ray analysis. In both compounds, dppm is a bridging
ligand between the two cluster units. Molecule3 can be considered as an unusual 12-membered macrocycle containing C, P, Cl, and Os atoms in the ring.

Photolysis of carboxamides of the dendrite structure with aminomethyland 1-aminoethylcymantrenes leads to the formation of six-membered dicarbonyl chelates with the Mn—O bond which are stable in solutions. The chelates in the reversed dark reaction with carbon monoxide give the starting tricarbonyl complexes. The formation of the chelates and their dark reaction are accompanied by the reversible change of color by the compounds. The rate determining step of the thermal reaction of chelates with CO is a chelate ring opening with the ligand substitution by the SN1 mechanism. A possibility of solvent-free photoinduced ligand-exchange reaction in a number of cymantrene derivatives was demonstrated. 相似文献

FTIR spectra have been studied for staircase cyclopentadienyl complexes comprising two or three metal carbonyl fragments bound by the metal-carbon bond Cp(CO)2Fe-CpmMn(CO)3 (1), Cp(CO)2Fe-CpmFe(CO)2CH2Ph (2), Cp(CO)2Fe-Cpm(CO)2Fe-CpmMn(CO)3 (3), Cp(CO)2Mo-Cpm(CO)2Fe-CpmMn(CO)3 (4), Cp(CO)3W- Cpm(CO)2Fe-CpmMn(CO)3 (5), Cp(CO)2Fe-Cpm(CO)2Fe-BmCr(CO)3 (6), Cr(CO)3Bm-CpmFe(CO)2CH2Ph (7), where Cp = 5-C5H5, Cpm = 15-C5H4, Bm = 16-C6H5, as well as mononuclear model complexes Cp(CO)2Fe(CH)2Ph (8), CpMn(CO)3 (9), and (6-C6H6)Cr(CO)3 (10). The spectra were interpreted on the basis of the local symmetry of each metal carbonyl center. The positions of vCOs are determined by the mutual electronic effect of each center. CpmM(CO)n groups are strong electron acceptors and cause an increase in vCOs of adjacent M(CO)n groups. Cp(CO)nM groups, being electron donors, cause a decrease in the frequencies of neighboring groups. In trinuclear complexes, the frequencies of the central Fe(CO)2 group are not changed much due to the compensation of donor and acceptor influences of two neighboring substituents.Translated fromIzvestiya Akademii Nauk.
