Novel organic-solvent-free aziridination of olefins: Chloramine-T–I2 system under phase-transfer catalysis conditions

Abstract
A variety of olefins could be aziridinated successfully by employing iodine-catalysed aziridination in water with a catalytic amount of a quaternary ammonium salt. Furthermore, the larger-scale process of styrene aziridination gives a highly pure aziridine in good yield via simple work-up.
