A series of 1,2, 4, 5-tetraaza-3-pentenes 4a-j were synthesized by the reaction of appropriate nitrilimines 2 with substituted hydrazines (H2NNHCOR, R=Ph, OMe) 3. Heating the compounds 4a-j with activated charcoal in refluxing benzene oxidized to formazans 5a-j and some formazans 5fj (R = OMe) gave s-tetrazinones 6fj in presence of lithium hydride. The microanalysis and spectral data of the synthesized compounds are in fall agreement with their molecular structure.

A series of 1,2,4,9,10,12-hexaazadispiro[4.2.4.2]tetradeca-2,10-dienes (5a-j) was synthesized by the reaction of 1,4-cyclohexanedione oxime 3 with appropriate nitrilimines 2. The microanalysis and spectral data of the synthesized compounds are in full agreement with their molecular structure. The microbial features of some of the synthesized compounds were studied by a known method.

The reaction of C-aroyl-N-arylnitrilimines II with Girard-reagent P III led to the formation of the 1,2,3,4-tetrahydro-1,2,4,5-tetrazin-3-ones IVa-f and 1,2,6,7-tetrahydro-1,2,4,5-tetrazepin-6-ones Va-f, which underwent thermal oxidation to 1,6-dihydro-1,2,4,5-tetrazin-6-ones and 6,7-dihydro-1,2,4,5-tetrazepin-6-ones. The microanalysis and spectral data of the synthesized compounds are in full agreement with their molecular structure.
