endocyclic nitrogen atom as well as on the amino group, giving 5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-4H-tetrazolo[1,5-a][1,3]diazepine. Under analogous conditions, 3-amino-1,2,4-triazole undergoes cycloalkylation of the neighboring N1 and N2 atoms of the heterocycle resulting in 1-amino-5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-[1,2,4]triazolo[1,2-a]pyridazinium perchlorate. The crystal structures of the products
发现5-氨基四唑与2,5-二甲基己烷-2,5-二醇在高氯酸中的烷基化同时在环内氮原子和氨基上进行,得到5,5,8,8-四甲基-5, 6,7,8-四氢-4 H-四唑[1,5- a ] [1,3]二氮杂。在类似条件下,3-氨基-1,2,4-三唑经历杂环的相邻N1和N2原子的环烷基化,从而生成1-amino-5,5,8,8-tetramethyl-5,6,7,8 -四氢- [1,2,4]三唑并[1,2一]哒嗪鎓高氯酸盐。通过单晶X射线分析确定产物的晶体结构。
