Abstract:3,6-Dicholo-1,2,4,5-tetrazine(BCT) was synthesized from 3,6- bis(3,5-dimethylpyrazol-1-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 ultralow temperature.
