Synthesis of a novel heterocyclic system—7-methyl-1,2-dihydro-[1,2,4]triazino[3,4-b][1,2,4,5]tetrazine-6-thione
摘要:
4-Amino-6-methyl-3-hydrazino-4,5-dihydro-1,2,4-triazine-5-thione reacted with triethyl ortho-formate or triethyl orthoaceate in ethanol to give a novel heterocyclic system, [1,2,4]triazino[3,4-b][1,2,4,5]-tetrazine-6-thione.
