Hyperactive: A benziodoxole triflate promotes iodo(III)cyclization of alkynes tethered to a variety of nucleophilic moieties, affording benziodoxole-appended (hetero)arenes such as benzofurans, benzothiophenes, isocoumarins, indoles, and polyaromatics. These unprecedented (hetero)aryl-IIII compounds are easy to purify, air- and thermally stable, and amenable to various synthetic transformations.
