Synthesis of 1H-[1,2,3]triazolo[4,5-e][1,2,3,4]tetrazine 4,6-dioxide and its methyl derivatives

1H-[1,2,3]Triazolo[4,5-e][1,2,3,4]tetrazine 4,6-dioxide (3) was synthesized by reduction of 1-hydroxy-1H-[1,2,3]triazolo[4,5-e][1,2,3,4]tetrazine 5,7-dioxide (1) with PCl3, reduction of 1-methoxy-1H-[1,2,3]triazolo[4,5-e][1,2,3,4]tetrazine 5,7-dioxide (4)

A Novel Hydrazino-transfer Reaction to a Saturated Carbon: Direct Conversion of Substituted Acetophenone and Aliphatic Ketone 4-Nitrophenylhydrazones into 1,2-Bis-hydrazones. Reactions of Mercury(II) Acetate with Nitrogen Compounds. Part 6

Treatment of a series of substituted acetophenone 4-nitrophenylhydrazones with mercury(II) acetate in acetic acid gave the corresponding substituted phenylglyoxal bis-(4-nitrophenylhydrazones) in varying yields.Similar reactions involving hydrazino-transfers to methyl groups were observed with the 4-nitrophenylhydrazones of acetone, propiophenone, methyl ethyl ketone, methyl benzyl ketone, and also with the 2,4-dinitrophenylhydrazones of acetone and acetophenone.Substituent influences on product distribution and a possible mechanism are discussed.
