Synthesis, structure, and catalytic activities of new Cu(i) thiocarboxylate complexes

Abstract

Thiobenzoate complexes of Cu(I), [Cu(SCOPh)]_n(1), [Cu(bpy)(µ-SCOPh)]₂ (2), [Cu(dppf)(SCOPh)] (3), [where bpy = 2,2′-bipyridyl; dppf = [1,1′-bis(diphenylphosphino)ferrocene] were synthesized and structurally characterized by X-ray crystallography. NBO calculations were performed to understand the nature of the Cu–Cu (2.706 Å) interaction in 2. All of the complexes were found to catalyze azide–alkyne cycloaddition for the regioselective synthesis of glycoconjugate triazoles under click reaction.
