Abstract

Abstract A metal-free, vinyl sulfone-based synthesis of 1, 5-disubstituted-1, 2, 3-triazoles is reported for the first time. These triazoles are easily formed in a regioselective fashion by heating under reflux a mixture of a substituted vinyl sulfone and an organic azide 'on water'. This powerful and practical route has the potential to be exploited for the synthesis of complex 1, 5-disubstituted-1, 2, 3-triazoles.
