microscopic techniques. This heterogeneous catalyst showed excellent activity in the click synthesis of 1,2,3-triazoles via one-pot three-component reaction of alkynes, organic halides, and sodium azide. Moreover, the catalyst was applied for synthesis of 1,2,3-triazoles by the reaction of α-bromoketones, alkyl/aryl terminal alkynes and sodium azide. The heterogeneous catalyst was reused several times
摘要在由三甲氧基甲硅烷基丙基氯化物,Cu(II)Br 2-官能化的纳米二氧化硅上负载的3,5-双(2-苯并噻唑基)吡啶铜(II)配合物Cu(II)Br 2 -BTP的制备报告了BTP @ TMSP-nSiO 2。所制备的催化剂通过不同的分析技术进行了表征,例如元素分析,FT-IR,1 H NMR,ICP-OES,XPS和UV-Vis光谱法,以及SEM和TEM显微技术。这种多相催化剂在炔烃,有机卤化物和叠氮化钠的一锅三组分反应中,在1,2,3-三唑的点击合成中表现出出色的活性。此外,通过α-溴代酮,烷基/芳基末端炔烃和叠氮化钠的反应,将该催化剂用于合成1,2,3-三唑。
