Reactions of the title compound and its arylmethylene derivatives include quaternization and subsequent formation of 4-substituted 1-amino-1,2,4-triazoline-5-thiones [1-amino-1H-1,2,4-triazole-5(4H)-thiones] and 1-amino-1,2,4-triazolin-5-ones[1-amino-1H-1,2,4-triazol-5(4H)-ones]. Acetylation products and a new class of fused heterocycles, 6-aryl-1-arylalkyl-7H-1,2,4-triazolo[3,2-b] [1,3,4]thiadiazin-1-ium salts, are presented.
