The reactions of the bicarbonatocopper(I) complex, (A, phen = 1,10-phenanthroline), with activated alkanes 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 complex, > (1), whereas in the presence of CO2 C-C coupling occurs to give the carboxylated derivative > (2).Complex 2 can be obtained by bubbling CO2 through solutions of 1.Complex 1 is readily formed when dinitrogen is bubbled through suspensions of 2 or when 2 is kept under vacuum at room temperature.Ethyl cyanoacetate reacts with A under an inert atmosphere to give > (3), and in the presence of carbon dioxide to give > (4).The latter can be also obtained by the action of Co2 on complex 3.The reaction of diethyl malonate with A gives the unexpected carboxylato complex > (4).The latter can be also obtained by the action of CO2 on complex 3.The reaction of diethyl malonate with A gives the unexpected carboxylato complex > (5) under nitrogen or under a carbon dioxide.A possible mechanism for formation 5 is discussed.

In the title complex, [CuI(C12H8N15P], phenanthroline acts as a bidentate ligand coordinating via two N atoms to copper. The coordination polyherdron around the Cu atom is a distorted tetrahedron, with a Cu-P distance of 2.1977 (9) A, Cu-N distance of 2.111 (3) and 2.071 (3) A, and a Cu-I distance of 2.6157 (6) A.
