Metal-free azaphosphaannulation of phosphonamides through intramolecular oxidative C-N bond formation

We report an efficient metal-free azaphosphaannulation of a myriad of phosphonamides through intramolecular oxidative C-N bond formation using PhI(OAc)2 and iodine in acetonitrile under air, thus leading to the formation of benzazaphosphol-3-on
