Differential formation of nitrogen-centered radicals leading to unprecedented, regioselective bromination of N , N ′-(1,2-phenylene)bisamides and 2-amidophenols

A highly efficient, site-selective, visible light-accelerated, remote C–H halogenation of unsymmetrical aromatic bisamides/amidoesters has been developed. Unprecedented selectivity was realized in this C–H functionalization reaction. The N , N ′-(1,2-phenylene)bisamides/amidoesters, derived from var...
