Synthesis of new triazole-based trifluoromethyl scaffolds

Beilstein Journal of Organic Chemistry, 2008
Trifluoromethyl propargylamines react with various azide derivatives to afford 1,4-disubstituted 1,2,3-triazoles through a Huisgen 1,3-dipolar cycloaddition. The reaction is catalyzed by a Cu(I) species in acetonitrile, and the corresponding products are
