REUSABLE POLYMER-SUPPORTED TERPYRIDINE COPPER COMPLEX FOR [3+2] HUISGEN CYCLOADDITION IN WATER

A polymer-supported terpyridine copper(I) complex was prepared and found to promote the Huisgen [3+2] cycloaddition reaction between azides and alkynes in water to give the corresponding triazoles with up to 87% isolated yield. This catalyst was recovered and reused several times without any loss in catalytic activity.
