An efficient method for the synthesis of 1,4-disubstituted triazoles in water at room temperature has been developed using CuCl2/Zn as a catalyst system. Under the optimized conditions, a novel series of 1,4-disubstituted 1,2,3-triazoles were synthesized.
Cu2O/CMP has been developed as a highly efficient catalytic system for Huisgen-click reaction in water at 60 °C.
