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.
