CH2(R)(R′) (R = R′ = CN; R = R′ = COOEt; R = CN, R′ = COOEt), in the presence and in the absence of carbon dioxide have been studied. Reaction of malonodinitrile with A under an inert atmosphere gives the organocopper complexex, [(phen)(Ph3P)CuCH(CN)2] (1), whereas in the presence of CO2 CC coupling occurs to give the carboxylated derivative [(phen)(Ph3]P)CuO2CCH(CN)2](2). Complex 2 can be obtained
