Modelling the Pichler–Schulz mechanism by catalytic hydrosilylation of acyl metal complexes
Abstract
Catalytic hydrosilylation of acetyl complexes, M–COMe affords α-siloxyethyl complexes, M–CH(OSiR3)Me, in quantitative yields; the hydrosilylation of an acetylmanganese complex, Mn(CO)5–COMe, produces C2–C4 alkenes by a repeating reduction–carbonylation sequence, which serves as a model reaction for the chain propagation step of the Pichler–Schulz mechanism.
