Reactions of a methylcopper complex CH<SUB>3</SUB>Cu(PPh<SUB>3</SUB>)<SUB>2</SUB>(diethyl ether)<SUB>0.5</SUB> (PPh<SUB>3</SUB>=triphenylphosphine) with three types of active hydrogen compounds HA give the corresponding copper derivatives of active hydrogen compounds formulated as ACu(PPh<SUB>3</SUB>)<SUB>2</SUB>. Nitroalkanes (nitromethane, nitroethane and 2-nitropropane) form copper complexes bonded through aci-nitro groups. β-Diketone and its analogs such as acetylacetone, diethyl malonate and ethyl acetoacetate react in their enol form to give six-membered <I>O</I>,<I>O</I>′-bonded chelates, whereas cyanoalkanes including acetonitrile, propionitrile, and malononitrile afford organocopper complexes having a direct Cu–C bond.
