Silicon powder was found, for the first time, to be an efficient alternative to transition metal catalysts for aminobromination of alpha,beta-unsaturated carbonyl compounds and simple olefins with p-toluenesulfonamide (4-TsNH2) and NBS, affording the aminobrominated products in high yields and regio- and stereoselectivity. The high reactivity of electron-rich substrates reveals that the reaction has the electrophilic addition feature.
