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 active N–H compounds HNR<SUP>1</SUP>R<SUP>2</SUP> give the corresponding copper derivatives formulated as R<SUP>1</SUP>R<SUP>2</SUP>NCu(PPh<SUB>3</SUB>)<I><SUB>n</SUB></I> (<I>n</I>=2 for R<SUP>1</SUP>R<SUP>2</SUP>N=phthalimido, succinimido, <I>N</I>-phenylacetamido (<B>4</B>), acrylamido, phenylamido, and 2-oxo-1-pyrrolidinyl; <I>n</I>=1 for R<SUP>1</SUP>R<SUP>2</SUP>N=acetamido). The IR and NMR spectroscopic data of the complexes support the bonding of the R<SUP>1</SUP>R<SUP>2</SUP>N group to Cu through nitrogen. The reactions of the Cu(I)–N complexes with alkyl and aryl halides (RX) afford the corresponding <I>N</I>-substituted compounds RNR<SUP>1</SUP>R<SUP>2</SUP> in high yields.
