    Description / Table of Contents: Titanium-, Zirconium- und Hafniumderivate von CobaltcarbonylenBimetallische und trimetallische Verbindungen mit M-Co-Bindungen (M = Ti, Zr, Hf) werden erhalten durch Reaktionen von R41-Derivaten (R1 = PhCH2; R22N; R2 = Me, Et) mit HCo(CO)4 (A) bzw. durch Umsetzung von R31MX-Derivaten (X = CI, Br; R1 = PhCH2, R22N und R3O; R3 = i-Pr, n-Bu) mit Na[Co(CO)4] (B). Dabei wurden Verbindungen des Typs R31MCo(CO)4 mit R1 = PhCH2, R2)2N und solche des typs R21M[Co(CO)4]2 mit R1 = PhCH2 nach den Methoden A und B gewonnen während (R3O)4-n Ti[Co(Co)4]n-Derivate (n = 1,2) nur gemäß Methode B zugängig waren.Phosphan- und Phosphitderivate der angeführten Verbindungen wurden erhalten bei Substitution von jeweils einer CO-Gruppe durch PR34-Liganden bzw. durch Reaktion von HCo(CO)3(PR34 mit R41M Verbindungen. Der Einfluß der Substituenten R1 und PR34 auf die Stabilität der Verbindungen wird diskutiert.
    Notes: Bimetallic and trimetallic compounds containing unsupported bonds of subgroup 4 metals (M = Ti, Zr, Hf) and Co were prepared by hydride elimination (A) from R41M derivatives (R1 = PhCH2; R22N; R2 = Me, Et)) and by salt elimination (B) from R31MX (X = Cl, Br; R.1 = PhCH2, R22N and R3O; R3= i-Pr, n-Bu)) by reaction with HCo(CO)4 and Na[Co(CO)4], respectively. Compounds R31MCo(CO)4 with R1 = PhCH2, R21M[Co(CO)4]2 R.1 = PhCH2, were prepared both by methods A and B, while (R3O)4-n Ti[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 PR34 ligand or by A type reaction of HCo(CO)3(PR34 with R41M compounds.
