1,3,4,5-Tetraamino-1,2,4-triazolium Cation: An Energetic Moiety

The amination of 3,4,5-triamino-1,2,4-triazole with O-tosylhydroxylamine yielded the nitrogen-rich 1,3,4,5-tetraamino-1,2,4-triazolium cation as its tosylate salt. Subsequent metathesis reactions produced energetic salts with various energetic anions, inc

Synthesis of 3,4,5-Triamino-4H-1,2,4-triazole (Guanazine) and its 4-Arylideneamino Derivatives

Synthetic methods for the preparation of 3,4,5-triamino-4H-1,2,4-triazole (guanazine) and its 4-arylideneamino derivatives are described.Guanazine, which can be used as an appropriate starting material in the syntheses of different bicyclic heterocycles, was readily obtained from thiosemicarbazide by treatment with mercuric oxide.Guanazine was also obtained from the S-methylisothio ether of thiosemicarbazide via a pyrolytic reaction.The 4-arylideneamino derivatives were either prepared by treatment of guanazine with an appropriate aromatic aldehyde, or by methods in which 1-arylidene-5-thiocarbamoyldiaminoguanidines are used as starting materials.
