4-Chlorostyrene → 2-(4-Chlorophenyl)-1-(4-nitrophenylsulfonyl)aziridine

Participants

Reaction Steps

To a suspension of 1-chloro-4-vinylbenzene (0.1195 ml, 0.9957 mmol), tetrakis(acetonitrile)copper(I) hexafluorophosphate (0.01856 g, 0.04979 mmol), and 4 angstrom molecular sieves (300 mg) in dry acetonitrile (2.5 ml) degassed with argon was added [N-[(p-nitrophenyl)sulfonyl]imino]phenyliodinane (0.6037 g, 1.494 mmol) portion-wise over 2 hours as a solid. It was stirred overnight under argon, then was loaded directly onto a Biotage SP1 system eluting with a 2-30% linear gradient of EtOAc in hexanes to yield 276 mg of the title compound (81.8% yield).
