Facile synthesis of diverse 1,4-disustituted 1,2,3-triazoles derivatives using readily accessible, cost effective, remarkably stable and easily tunable 1,2,3 triazole based ligand, (1-(4-Methoxybenzyl)-1-H-1,2,3-Triazol-4- yl)Methanol (MBHTM) in PEG-H2O as green reaction media has been developed . As compared to ligand free reaction, the dramatic rate enhancement of copper catalyze azide–alkyne cycloaddition (CuAAC) at low catalyst loading in PEG-H2O media has been observed. The present method provides high to excellent yields and thus considered to be the green “click chemistry” tool for synthetic applicationsc
