2,4-Dialkyl Substituted Carbono- and Thiocarbonohydrazides, Reactions with Carbonyl Compounds

2,4-Dialkyl substituted carbono- and thiocarbonohydrazides (4) were prepared from alkylhydrazines and phosgene or thiophosgene.Mono carbonyl compounds reacted with 4 (molar ratio 1:1) to yield hexahydro-1,2,4,5-tetrazines (9, 14; exception 13).Aldehydes in excess generally afforded dihydrazones (3); formaldehyde, however, yielded 1,1'-methylenebis(hexahydro-1,2,4,5-tetrazines) (10) as well as the bicyclic compounds 11 and 12.The constitution of 11 was confirmed by X-ray analysis of 11b.Dialdehydes and aliphatic or alicyclic α-diketones reacted with 4 to give double hexahydro-1,2,4,5-tetrazine derivatives (19), aryl substituted α-diketones on the other hand yielded cyclic dihydrazones (15) and/or mono-hexahydro-1,2,4,5-tetrazines (16).
