Reaction of N-Halosulfonamide. III. Reaction of N, N-Dibromobenzenesulfonamide with Cyclopentene.

Abstract

Reaction of N, N-dibromobenzenesulfonamide (I) with cyclopentene (II) was investigated and it was shown that N-(DL-trans-2-bromocyclopentyl) benzenesulfonamide (III), DL-trans-1, 2-dibromocyclopentane (V), cyclopentadiene (VI) and benzenesulfonamide (VII) were formed on the reaction. Contrary to the case of reacting I with cyclohexene, DL-cis isomer of III could not be obtained in the present case.
