摘要：

Bimetallic and trimetallic compounds containing unsupported bonds of subgroup 4 metals (M = Ti, Zr, Hf) and Co were prepared by hydride elimination (A) from R4(1)M derivatives (R1 = PhCH2; R2(2)N; R2 = Me, Et) and by salt elimination (B) from R3(1)MX (X = Cl, Br; R1 = PhCH2, R2(2)N and R3O; R3 = i-Pr, n-Bu) by reaction with HCo(CO)4 and Na[Co(CO)4], respectively. Compounds R3(1)MCo(CO)4 with R1 = PhCH2, R2(1)M[Co(CO)4]2 R1 = PhCH2 were prepared both by methods A and B, while (R3O)4-nTi[Co(Co)4]n (n = 1, 2) compounds were obtained by reaction B. Several tertiary phosphine and phosphite derivatives of the former two types were obtained by substitution of a carbonyl group by PR3(4) ligand or by A type reaction of HCo(CO)3(PR3(4)) with R4(1)M compounds.
