A magnetically separable ruthenium catalyst was synthesized through immobilizing a pentamethylcyclopentadienyl ruthenium complex on iron oxide nanoparticles. The catalyst is highly active and selective for the synthesis of 1,5-disubstituted 1,2,3-trizoles via cycloaddition of alkynes and organic azides and can be recycled at least 5 times.
通过将五甲基环戊二烯基钌络合物固定在氧化铁纳米颗粒上来合成可磁分离的钌催化剂。该催化剂对炔烃和有机叠氮化物的环加成反应具有很高的活性,对合成1,5-二取代的1,2,3-三唑具有选择性,可循环使用至少5次。
