Popis: |
Imination and amidation of sulfides, sulfoxides, and olefins using 4H-1,2,4-triazole-4-amine as a nitrogen source with PhI(OAc)2 as an oxidant were achieved in moderate to high yields without the addition of a catalyst. The carbon–nitrogen and sulfur–nitrogen bond forming reactivity is consistent with a nitrene insertion mechanism in which the reactivity generally increases with decreasing N–H bond dissociation energy of the nitrogen source and increasing oxidation potential of the oxidant. |
