Azide–alkyne cycloaddition reactions in water <i>via</i> recyclable heterogeneous Cu catalysts: reverse phase silica gel and thermoresponsive hydrogels
Functionalized reverse phase silicagel and thermoresponsive hydrogels were synthesized as heterogeneous catalysts supports. Cu(I) and Cu(II) catalysts immobilized onto two types of supports were prepared and characterized. The copper catalyzed azide–alkyne cycloaddition was performed in water via a one-pot reaction and yielded good results. These catalysts are air stable and reusable over multiple
合成了功能化的反相硅胶和热响应水凝胶作为非均相催化剂载体。制备并表征了固定在两种载体上的Cu( I ) 和 Cu( II ) 催化剂。铜催化的叠氮化物-炔烃环加成反应在水中通过一锅反应进行,并产生了良好的结果。这些催化剂对空气稳定且可多次使用。
