Abstract

Photolysis of CpRe(CO)3 in the presence of dichloromethane results in the initial formation of the CpRe(CO)2(ClCH2Cl) complex followed by insertion of the metal into the C-Cl bond. The activation enthalpy is determined to be 20.4 kcal/mol, and with the assistance of DFT calculations, a radical mechanism is proposed for the oxidative addition reaction. Photolysis of Ni(CO)2(PPh3)2 with dihalomethanes also results in oxidative addition, but the intermediacy of a halogen-bound adduct has not been established.
