diazo group transfer reaction with p-tosyl azide. It was found that alkylation of sodium 1-aryl- and 1-arylmethyleneamino-1,2,3-triazol-5-olates 7, 4 with methyl iodide, benzyl chloride or substituted phenacyl bromides results in 3-alkyltriazol-3-ium-5-olates 8, 9 that are compounds of mesoionic structure. In contrast, alkylation of 1-arylsulfonyl-substituted triazoles 6 with methyl iodide leads to
的新衍生物 1 H -1,2,3-三唑 4,6,7是从由丙二酸衍生物制备重氮基团 与转移反应 对甲苯磺酰叠氮化物。发现烷基化的钠1-芳基-和1-芳亚甲基-1,2,3-三唑-5- olates 7,4与甲基碘, 苄基氯或取代的苯甲酰甲基溴化物导致3- alkyltriazol -3-鎓-5- olates 8,9是介离子结构的化合物。相比之下,烷基化 1-芳基磺酰基取代的 三唑 6与甲基碘导致2-甲基-1,2-二氢-1,2,3-三唑-5-酮12。水解 的 甲亚胺 9 提供1-氨基三唑10,然后可以将其脱氨基亚硝酸 或者 亚硝酸丁酯得到1-烷基-4-羟基三唑11。
