ABSTRACT A highly efficient and environmentally friendly one-pot procedure for the synthesis of 1,2,3-triazoles by 1,3-dipolar cycloaddition of benzyl halides, terminal alkynes, and sodium azide over LaCuxMn1-xO3 perovskite oxides was developed. LaCu0.7Mn0.3O3 was found to be active with low catalyst loading under ultrasonic irradiation in aqueous media. The reaction was performed efficiently in the presence
摘要 开发了一种高效、环保的一锅法,用于在 LaCuxMn1-xO3 钙钛矿氧化物上通过苄基卤化物、末端炔烃和叠氮化钠的 1,3-偶极环加成反应合成 1,2,3-三唑。发现 LaCu0.7Mn0.3O3 在水介质中超声辐照下具有低催化剂负载量的活性。在没有任何添加剂或碱的情况下,在纳米催化剂的存在下,反应有效地进行,反应时间显着减少。催化剂可以循环使用至少5次,对反应结果没有任何显着影响。此外,使用二硫化碳和三(三甲基甲硅烷基)甲基锂合成了一系列新型有机硅硫取代的 1,2,3-三唑衍生物。图形概要
