Chemo- and regioselective protocols for attachment of various carbonyl functionalities onto unactivated olefins have been developed. Atom transfer radical reactions of Cl3CCN, Cl2C(R)CN, and Cl2C(CN)2 were all promoted efficiently by a catalytic amount of CuCl and 1,1′-bis(diphenylphosphino)ferrocene to introduce chloromethylcyanide and chloride units to the C–Cdoublebonds. Conversion of the chloromethylcyanide
