The selective diamination of arylcyclobutanes was achieved by rhodium(II) catalysis using N-fluorobenzenesulfonimide as the oxidant and nitrogen source.
Activated by multiple consecutive oxidative radical-polar crossover and desaturation processes, the selective diamination of arylcyclobutanes, which is difficult to perform by classical metallonitrene C-H insertion, was achieved in a short time by rhodium(II) catalysis using N-fluorobenzenesulfonimide (NFSI) as the oxidant and nitrogen source.
