- 中文摘要: Reaction of 6-mercapto-7H-1,2,4-triazolo[1,5-d]tetrazole (1) wtih 1,2-phenylenediamine afforded N-{7H-1,2,4-triazolo[1,5-d]tetrazol-6-yl}-1,2-phenylenediamine which was cyclized to benzimidazolyl-1,2,4-triazolo[1,5-d]tetrazoles using various one-carbon cyclizing agents. Also, the treatment of 1 with maleic anhydride or phthalic anhydride gave the corresponding thio derivatives followed by hydrazinolysis to afford the thio heterobicyclic systems. Former structures of the products have been established upon elemental and spectral analyses.
