Abstract

An efficient one-pot reaction of acid chlorides, terminal acetylenes, sodium azide and aryl halides is developed for the regioselective synthesis of 2,4,5-trisubstituted 1,2,3-triazoles. The method is general, convenient, eco-friendly, atom-economical, and could provide excellent yields and regioselectivities.
