A number of triazolotriazine and triazinotetrazine derivatives have been prepared. 3-(2-Benzylidene-1-methylhydrazino)-6-methyl-5-oxo-4-triphenylphosphoranylideneamino-4,5-dihydro-1,2,4-triazine (3), available from the iminophosphorane (2) and benzaldehyde, reacts with aliphatic isocyanates at room temperature to give the corresponding 8H-triazolotriazinones (6)-(12).On the other hand, iminophosphorane (2) reacts with acyl chlorides at room temperature to give 3-(2-acyl-1-methylhydrazino)-6-methyl-5-oxo-4-triphenylphosphoranylideneamino-4,5-dihydro-1,2,4-triazines (13)-(15), which react with isocyanates at room temperature to give 2H-triazinotetrazines (17)-(24).
