以2,5-二巯基-1,3,4-噻二唑为原料,与水合肼缩合,生成2,5-二肼基-1,3,4-噻二唑。2,5-二肼基-1,3,4-噻二唑与对乙氧基苯四酰氯反应,再以POC l3为环合剂环合酰肼基-1,3,4-噻二唑,得到3,6-二对乙氧基苯基-1,2,4-三唑[3,4-b]1,2,4-三唑并1,3,4-噻二唑,合成的此化合物未见报道,其结构通过元素分析、红光光谱、核磁共振氢谱和质谱予以证实。
2,5-dimercapto-1,3,4-thiadiazole as raw material, and hydrazine hydrate condensation, 2,5-dihydrazino-1,3,4-thiadiazole. 2,5-dihydrazino-1,3,4-thiadiazole and p-ethoxy benzene four acid chloride, and then POCl3 ring-closure agent hydrazide-1,3,4-thiadiazole, 3,6-di-p-ethoxyphenyl-1,2,4-triazole [3,4-b] 1,2,4-triazole and 1,3,4-thiadiazole were synthesized, Compounds have not been reported, and their structures were confirmed by elemental analysis, red light spectrum, 1H-NMR and MS.
