SYNTHESIS, STRUCTURE AND CHARACTERIZATION OF COPPER(I,II) COMPLEXES

Four copper( II) complexes were synthesized at room temperature by oxi dative addition reaction of metallic copper powder and dibenzoyl perox ide in the presence of ligands(2,2'-bipy,dppe, 2 -aminopyridine and be nzoimidazole, respectively). Four copper( I) complexes were synthesize d by reduction substitution reaction of copper( II)salts with differen t diphosphine ligands[Ph2P(CH2)(n)PPh2, dppm(n =1),dppe(n =2),dppp(n = 3)and dppb(n =4)]. The complexes were characterized by elemental analy sis and single crystal X-ray analysis. The reaction mechanism was disc ussed on the basis of electronic spectra. A facile synthetic method of copper(I,II) complexes was provided.
