A new series of heteroleptic binuclear Cu(I) bis(salicylidene)hydrazone complexes (1-4) bearing triphenylphospine coligands have been synthesized from the reactions of copper(II) precursor complex [CuCl2(PPh3)2] with oxadiazole compounds A-D, respectively. It has been observed that the oxadiazole compounds undergo ring cleavage with in situ reduction of Cu(II) ion, during the formation of complexes (1-4). The oxadiazoles (A-D) and the Cu(I) complexes (1-4) have been characterized by analytical and spectroscopic methods. Single crystal X-ray diffraction study of complex 2 has revealed a distorted tetrahedral geometry around each Cu(I) center. Catalytic efficiency of the new complexes on the N-alkylation of amines using alcohols was studied under optimized conditions. The new complexes have also been tested for their catalytic activity towards the direct N-alkylation of 2-nitropyridine.

Three multifunctional ligands containing 2,5-disubstituted-oxadiazole units including an ortho/meta/para-substituted pyridine moiety have been synthesized. The reactions of the ligands with zinc(II) acetate in pyridine gave crystalline complexes with the

Unsymmetrically 2,5-disubstituted 1,3,4-oxadiazoles were efficiently synthesized from the cyclization-oxidation reaction of acyl hydrazones. Also, the synthesis of the title compounds was achieved by the condensation of acyl hydrazides and aromatic aldehydes in the presence of ceric ammonium nitrate in dichloromethane.
