Abstract: By the condensation of 3-(1H-benzotriazole-1-methylene)-4-amino-5-mercapto-l,2,4-triazole with substituted benzoic acids in the presence of phosphorus oxychloride,ten novel 3-(1H-benzotriazoles)were obtained. Their structures were determined by elementary analysis, IR,1HNMR and MS. Their spectral properties were also discussed.

Key words: 1,2,4-Triazolo(3,4-b)-1,3,4-thiadiazole, Synthesis, Spectral property
