Synthesis of 1-aryl(hetaryl)-1,2,3-triazoles with the use of ionic liquids

Abstract

1-Phenyl(furazanyl)-1,2,3-triazoles can be synthesised by the 1,3-dipolar cycloaddition of phenylazide1or 4-amino-3-azidofurazan2to acetylenes (or to 1-morpholinyl-2-nitroethene for2) in ionic liquids {1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF ₄ ]) for1or 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF ₆ ]) for2}.
