Treatment of C-(triphenylphosphinimido)hydrazone (1) with aryl and alkyl isocyanates results in 5-arylamino- and 5-alkylamino-1H-1,2,4-triazoles (5), often accompanied by a minor quantity of the triazol-5-one (7).The related ortho-acyl-substituted substrates (8) react with phenyl isocyanate to give triazoloquinazolines (12) or (13) through the intermediacy of aminotriazoles (11).
