An efficient synthetic method for aromatic triazoles accelerated by rpolymer-supported CuI as catalyst between organic azides and terminal alkynes has developed. Treatment of terminal alkynes with benzyl azide or aryl azides in water smoothly gave the Huisgen 1, 3-dipolar cycloaddition products, triazoles. The novel Cu (Ⅰ) complex has shown good activity and stability after eight catalytic cycles.
