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

Photochemical reactionsbetween [Mn2(CO)8(PR3)]2](R = Et, Bun, OEt) and alkylhalides (R′X) proceed to completion in 2 to 4 h yielding equimolar quantities of [MnR′(CO)4PR3] and [MnX(CO)4PR3], by a route involving reaction of R′X with mononuclear intermediates.
