Photochemical reactionsbetween [Mn2(CO)8L2] (L = CO, PBu3, PEt3, P(OMe)3, P(OPh)3, PPh3) and alkylhalides (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 dinuclearcomplex and metal—metalbond homolysis of the coordinatively
