The condensation of N-phenyl-N'-(2-hydroxylphenyl)urea or N-phenyl-N'-(2-aminophenyl)urea with tris(dialkylamino)phosphine afforded derivatives of 4,5-benzo-1,3,2-oxaza (or diaza)-phospholane which formed intramolecular hydrogen bond.The cleavage of the amide bond to give N,N-dialkyl-N'-phenylurea together with polymers of 1,3,2-benzodiazaphosphole was observed in the latter reaction.
