An efficient copper iodide-catalyzed aziridination of a variety of alkenes with sulfonamides and sulfamate esters as the nitrogen source and iodosylbenzene (PhIO) as the oxidant is reported herein. The reaction is operationally straightforward, applicable to a variety of alkenes containing electron-withdrawing, electron-donating, and sterically encumbered substrate combinations, and proceeds under
