Abstract

The iodine(III) catalyst, in situ generated from iodoarene as a precatalyst with m-CPBA and Tf <subscript>2</subscript> NH, promoted the metal-free [2 + 2 + 1] cycloaddition-type reactions of alkynes, nitriles, and oxygen atoms for the regioselective formations of 2,4-disubstituted and 2,4,5-trisubstituted oxazole. A first example of iodine catalysis for multicomponent reactions is represented.
