000141269 520__ $$aKinetic and spectroscopic analyses were performed to gain  information about the mechanism of atom-transfer radical  reactions catalyzed by the complexes [RuCl2Cp*(PPh3)] and  [RuClCp*(PPh3)2] (Cp*=pentamethylcyclopentadienyl), in the  presence and in the absence of the reducing agent  magnesium. The reactions of styrene with ethyl  trichloroacetate, ethyl dichloroacetate, or  dichloroacetonitrile were used as test reactions. The  results show that for substrates with high intrinsic  reactivity, such as ethyl trichloroacetate, the oxidation  state of the catalyst in the resting state is +3, and that  the reaction is zero-order with respect to the halogenated  compound. Furthermore, the kinetic data suggest that the  metal catalyst is not directly involved in the rate- limiting step of the reaction.
