Aryl iodide mediated aziridination of alkenes

Aryl iodide mediated aziridination of a variety of alkenes with N-aminophthalimide under mild conditions (m-CPBA, K(2)CO(3), CH(2)Cl(2), 25 degrees C) was achieved in moderate to good yields (up to 94%). By recovering the aryl iodide, a recyclable system is developed with product yield over 79% attained for the aziridination of trans-1,2-diphenylethylene.
