N-Acylanilides having electron-donating substituents attached at a proper position react with phosphorus (III) bromides forming the new heterocyclic system - 2,4,1-benzoxazaphosphinine. 1-Arylamino-2,4,1-benzoxazaphosphinines are hydrolyzed with cleavage of an oxazaphosphinine ring affording mixed amides of 2,4-diaminophenylphosphonic acid in high yield.
