Synthesis and characterization of arylcopper compounds containing the methoxy or dimethylamino groups as a built-in ligand

The synthesis and isolation of 2, 6-dimethoxy-, 2,4,6-trimethoxy-, 2-(dimethylamino)- and 4-(dimethylamino)-phenylcopper are described. The dimethylamino-substituted phenylcopper compounds form complexes with cuprous bromide.In the case of insoluble compounds a polymeric structure is proposed in which each aryl group bridges two copper atoms by 2e-3c bonds with additional interchain Cu--N (or Cu--O) coordination
