Microwave Assisted Rapid Synthesis of (Arylselanyl)phenyl-1H-1,2,3-triazoles by Copper Catalyzed 1,3-Dipolar Cycloaddition

We describe here a simple and rapid protocol for the synthesis of (arylselanyl)phenyl-1H- 1,2,3-triazoles by copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions using Microwave Irradiation. The products were obtained under mild conditions in excellent yields in a short reaction time by reacting azidophenyl arylselenides with a range of terminal alkynes using catalytic amount of Cu(OAc)2.H2O/sodium ascorbate. This Click Chemistry protocol is an efficient method to synthesize new selenium compounds with potential application in biological studies and materials sciences.
