摘要
以3,6-双(3,5-二甲基吡唑)-1,2,4,5-四嗪为起始原材料,经肼基取代、氧化脱氮生成了3,6-二氯-1,2,4,5-四嗪,通过红外、核磁、质谱以及元素分析鉴定了化合物的结构,在优化合成工艺条件下,两步总收率达到70%,在超低温的条件下对产品进行了精制,纯度达到了99.2%以上。
3,6-Dicholo-1,2,4,5-tetrazine(BCT) was synthesized from 3,6- bis(3,5-dimethylpyrazol-l-yl)-1 ,2,4,5- tetrazine after substitution and oxidation. Its structure was characterized by IR, MS, ^13C NMR and elemental analysis. In addition, the synthetic procedure of BCT was optimized. The best condition of oxidation reaction was obtained as follows: reaction time was 15 min, content of water 0.08%, and the overall yield 70%. The purity of the product was 99.2% after the refined at the uhralow temperature.
