Binuclear Cu(I) complex of (N′1E,N′2E)-N′1,N′2-bis(phenyl(pyridin-2-yl)methylene)oxalohydrazide: Synthesis, crystal structure and catalytic activity for the synthesis of 1,2,3-triazoles
چکیده انگلیسی


• A novel binuclear Cu(I) complex has been synthesized for the first time.
• Structure of the complex was determined by X-ray crystallography.
• The complex was explored as an efficient catalyst for the synthesis of 1,2,3-triazoles.
• The complex exhibited excellent catalytic activity at very low catalyst loading.
• This offers triazole ring formation involving click reaction at room temperature.

A new binuclear 5-coordinate distorted trigonal bipyramidal Cu(I) complex with (N′1E,N′2E)-N′1,N′2-bis(phenyl(pyridin-2-yl) methylene) oxalohydrazide (H2bpoh) has been synthesized, and characterized by spectroscopic and single crystal X-ray diffraction techniques. In the complex, H2bpoh acts as a dibasic hexadentate ligand bonding with two Cu(I) each through a carbonylate-O, azomethine-N, and pyridyl-N atoms. The complex possess a CuN2OP2 core with a considerable delocalization of charge on the five-membered chelate rings which forms an unusual intra-molecular π–π stacking and CH⋯π interactions. The synthesized complex exhibits excellent catalytic efficiency for a click reaction at room temperature.
