The comparative reactivity of heterocyclic diazo compounds and the corresponding diazonium salts in C-azo coupling reactions was studied using imidazole, pyrazole, and triazole derivatives as examples.The reactivities of pyrazole- and imidazole-derived diazonium salts are much lower than those of thiadiazole- and 1,2,4-triazole-derived diazonium salts but higher than those of pyrrole and indole diazo
以咪唑、吡唑和三唑衍生物为例,研究了杂环重氮化合物和相应的重氮盐在C-偶氮偶联反应中的反应活性。吡唑和咪唑衍生的重氮盐的反应性远低于噻二唑-和 1,2,4-三唑衍生的重氮盐,但高于吡咯和吲哚重氮化合物。
