(DHQD)2PHAL ligand-accelerated Cu-catalyzed azide–alkyne cycloaddition reactions in water at room temperature
Abstract
Herein, we have described, a ‘Click Chemistry’ protocol for the rapid synthesis of 1,2,3-triazoles in water. (DHQD)2PHAL has been found to be an excellent accelerating ligand for the copper(I)-catalyzed azide–alkyne cycloaddition reaction under air. The procedure is simple, efficient, environmentally-friendly and the products were isolated in excellent yields with high purity.
