1,2,3-Triazolium salts draw much attentions in recent years. We developed a new synthetic method to heteroatom-functionalized triazoliums via nucleophilic substitution of 4-bromomethyltriazolium. This method afforded triazoliums with different S, N, and O heteroatom-substituents. Moreover, SN2′ reaction was observed with alcohols or hydroxides. In addition, debromination and debromomethylation reaction
近年来,1,2,3-三唑鎓盐备受关注。我们开发了一种新的合成方法,用于通过4-溴甲基三唑的亲核取代作用来杂原子官能化的三唑。该方法提供了具有不同S,N和O杂原子取代基的三唑鎓。此外,观察到与醇或氢氧化物的S N 2'反应。另外,在某些情况下发生脱溴和脱溴甲基化反应。
