‘Click’ cycloaddition catalysts: copper(i) and copper(ii) tris(triazolylmethyl)amine complexes

Abstract
The CuI complex of the ‘click’ ligand tris(benzyltriazolylmethyl)amine is an unusual dinuclear dication with one triazole unit bridging two metal centers, and is an effective catalyst for the ‘click’ cycloaddition reaction.
