Abstract
A catalyst-free electrophilic aminobromination system was described with N-methyl-p-toluenesulfonamide (p-TsNHCH3) and N-bromosuccinimide (NBS) as nitrogen and bromine resources. The reaction can give vicinal haloamines in good yields, excellent regioselectivities, and stereoselectivities under convenient and mild condition. The existence of N-methyl group in the nitrogen resource was found to play an important role in the formation of vicinal haloamine product.
