Kinetic investigation of the mixed-metal bimolecular reductive eliminations in the reactions of EtOC(O)CH2M(CO)n or EtOC(O)M(CO)n (M = Co, n = 4; M = Mn, n = 5) with HCo(CO)4 or HMn(CO)5

The alkyl- and acylmetal carbonyls EtOC(O)CH2M(CO)n and EtOC(O)M(CO)n (M = Co, n = 4; M = Mn, n = 5) react with HCo(CO)4 or HMn(CO)5 to yield ethyl acetate or ethyl formate and the corresponding binuclear metal carbonyl. Kinetic experiments support a mechanism according to which the reaction between a coordinatively unsaturated alkyl- or acylmetal carbonyl (formed by CO loss) and the metal carbonyl hydride is rate determining. The rate of this bimolecular reductive elimination step varies strongly and unexpectedly in the mixed-metal systems.

The silylidyne tricobalt clusters RSiCo3(CO)9 (1, R = Me, Ph, p-Tol) proved to be too sensitive for the conversion to mixed metal clusters by the reported metal exchange procedures.Therefore for the purpose of cluster construction the functional complexes RSiH2 - MLn (2 - 7, MLn = CrCp(CO)3, MoCp(CO)3, WCp(CO)3, Mn(CO)5, FeCp(CO)2, Co(CO)4) were prepared from RSiH2Br (R = Me, Ph) and carbonyl metalates.Their reaction with Co2(CO)8 produced the open trinuclear complexes R(MLn)SiCo2(CO)7 (8 - 10) only for MLn = MoCp(CO)3, WCp(CO)3, and FeCp(CO)2.Subsequent thermolysis resulted in the case of MLn = MoCp(CO)3 and WCp(CO)3 in the mixed metal clusters RSiCo2MCp(CO)8 (11, 12, M = Mo, W).
