Abstract

The mechanism of the known reaction between Co2(CO)8 and Et3SiH leading to Et3SiCo(CO)4 and H2 has been reinvestigated. In contrast to earlier reports, HCo(CO)4 is not an intermediate of this reaction. Catalytic amounts of pyridine or tributylphosphine increase the rate and change the kinetics of the reaction. A general scheme involving cobalt carbonyl radical species is proposed for the mechanisms of the uncatalyzed and catalyzed reaction pathways.
