from readily-available aryl–alkyl ketones (or alcohols) and different organic azides. Moreover, the reaction used environmentally friendly dimethyl carbonate (DMC) as the solvent and air as the oxidant, and H2O was the only by-product, so it provides a green and practical synthetic method for 1,2,3-triazoles.
已经开发了一种 Cu/TEMPO 催化的串联多重氧化脱氢和环加成反应,它可以从容易获得的芳基-烷基酮中得到 4-酰基-1,2,3-三唑和 4-二酮-1,2,3-三唑(或醇)和不同的有机叠氮化物。此外,该反应以环境友好的碳酸二甲酯(DMC)为溶剂,空气为氧化剂,副产物为H 2 O,为1,2,3-三唑类化合物的合成提供了一种绿色实用的方法。
