Reactions of a methylcopper complex CH3Cu(PPh3)2(diethyl ether)0.5 (PPh3 = triphenylphosphine) with active N-H compounds HNR¹R² give the corresponding copper derivatives formulated as R¹R²NCu(PPh3)n (n = 2 for R¹R²N = phthalimido, succinimido, N-phenylacetamido (4), acrylamido, phenylamido, and 2-oxo-1-pyrrolidinyl; n = 1 for R¹R²N = acetamido).The IR and NMR spectroscopic data of the complexes support the bonding of the R¹R²N group to Cu through nitrogen.The reactions of the Cu(I)-N complexes with alkyl and aryl halides (RX) afford the corresponding N-substituted compounds RNR¹R² in high yields.
