Catalyst-free and metal-free electrophilic bromoamidation of unactivated olefins using the N-bromosuccinimide/sulfonamide protocol.

An efficient, catalyst-free, and metal-free bromoamidation of unactivated olefins has been developed. 4-(Trifluoromethyl)benzenesulfonamide and N-bromosuccinimide were used as the nitrogen and halogen sources, respectively. The methodology is applicable to both cyclic and aliphatic olefins.
