A polymer supported ascorbate functionalized task specific ionic liquid: an efficient reusable catalyst for 1,3-dipolar cycloaddition

Abstract

A novel polymer supported ascorbate functionalized task specific ionic liquid was designed and synthesized. It has been demonstrated that the synthesized polymer supported ionic liquid acts as an efficient catalyst for regioselective Huisgen 1,3-dipolar cycloaddition of aryldiazonium tetrafluoroborate, sodium azide and terminal alkyne, which provide a series of 1,4-disubstituted-1,2,3-triazoles in high yields at room temperature as well as showing an aptitude for in situ incorporation of copper.
