Abstract

The potential of several alkylcobalt complexes as catalysts for hydrogenation and isomerization of alkenes has been investigated. The complexes CH₃Co(CO)₂(Pom-Pom) (Pom-Pom = 1,2 bis(dimethoxyphosphino)ethane), CH₃Co(CO)₃P(OMe)₃ and C₆H₅CH₂Co(CO)₃PPh ₃ are compared to CH₃Co(CO)₂(P(OMe)₃)₂, for their ability to function in catalytic cycles. Each is active for hydrogenation and isomerization of alkenes under conditions where the carbonylation-decarbonylation equilibrium is readily established. The lifetime for the complexes is much shorter than for CH₃Co(CO)₂ (P(OMe)₃)₂ suggesting that two phosphorus donors in trans positions in an intermediate is a requirement for catalyst stability in these alkylcobalt complexes.
