HYDROSILYLATION REACTIONS CATALYZED BY DECACARBONYLDIMANGANESE(0)

Decacarbonyldimanganese(O) complex, Mn//2(CO)//1//0, has been evaluated as a catalyst for hydrosilylation reactions of 1-hexane with tertiary silanes, Et//3SiH and (EtO)//3SiH. The reaction of Et//3SiH appears to be first order with respect to the catalyst, to the hexene and to the silane, although catalyst deactivation occurs when relatively high silane concentrations are used. The reaction rate is slightly affected by varying the type of the silane used. The rate of disappearance of the tertiary silane is consistent with that of the 1-hexene, which means that the catalyst is selective to hydrosilylation reactions.
