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

Abstract

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.
