摘要：

Photochemical reactions between [Mn2(CO)8L2] (L = CO, PBu3, PEt3, P(OMe)3, P(OPh)3, PPh3) and alkyl halides (RX) yield both alkyl and halo complexes, [MnR(CO)4L] and [MnX(CO)4L], in equimolar quantities. Kinetic and quantum yield studies suggest that these reactions proceed by a radical chain pathway involving CO dissociation from the dinuclear complex and metal-metal bond homolysis of the coordinatively unsaturated dinuclear intermediate. © 1990.
