activity in the multi-component synthesis of 1,4-disubstituted 1,2,3-triazoles by the click reaction of propargyl bromide, aromatic azides, and amines at room temperature. The advantages of this method are high reaction yield, short reaction time, and capability of recovering and reusing the catalyst. In addition, water, as a green medium, is used not only in the synthesis of 1,2,3-triazoles but also in
摘要 PVC负载的乙二胺-铜(II)络合物(PVC–EDA–Cu +2)为点击化学提供了高效,活性和可重复使用的非均相催化剂。在这项工作中,通过PVC,乙二胺和CuCl 2 ·2H 2的反应可轻松制备PVC-EDA-Cu +2催化剂O在水中。然后通过不同的分析工具表征催化剂的结构。该催化体系在室温下通过炔丙基溴,芳族叠氮化物和胺的点击反应在1,4-二取代的1,2,3-三唑的多组分合成中显示出高活性。该方法的优点是反应产率高,反应时间短以及催化剂的回收和再利用能力。另外,作为绿色介质的水不仅用于合成1,2,3-三唑,而且还用于制备催化剂。还针对两种革兰氏阳性和革兰氏阴性细菌菌株筛选了许多新的1,2,3-三唑衍生物。 图形概要
