Charcoal impregnated with zinc was able to catalyze the cycloaddition of organic azides and alkynes to provide the corresponding 1,4-disubstituted 1,2,3-triazoles and 1,4,5-trisubstituted 1,2,3-triazoles in good to excellent yields. Noteworthy was that the novel and heterogeneous catalyst was successfully applied in this cycloaddition reaction for the first time and could also be easily recycled.
用锌浸渍的木炭能够催化有机叠氮化物和炔烃的环加成反应,以提供相应的 1,4-二取代 1,2,3-三唑和 1,4,5-三取代 1,2,3-三唑产量。值得注意的是,该新型多相催化剂首次成功应用于该环加成反应中,且易于回收利用。
