nanoparticles for Suzuki and Heck reactions
Mizoroki-Heck. Various aryl halides were coupled with arylboronicacid (Suzuki cross-coupling reaction) and olefins (Heck reactions) under the green conditions to provide corresponding products in high to excellent yields. Interestingly, the catalyst can be easily isolated from the reaction media by magnetic decantation and can subsequently be applied for consecutive reaction cycles (at least seven times)
一种由葡糖胺功能化磁性 Fe 3 O 4 @SiO 2稳定的新型磁性和多相钯基催化剂合成了纳米颗粒。该策略依赖于葡糖胺与氰尿酰氯官能化磁性纳米粒子的共价键合,然后与钯络合。通过FT-IR、XRD、DLS、FE-SEM、TEM、ICP、UV-Vis、TGA、VSM和EDX完全确定了磁性纳米催化剂的结构。所得结果证实,由固定在磁性载体上的葡糖胺稳定的钯纳米颗粒在 Suzuki-Miyaura 和 Mizoroki-Heck 的交叉偶联反应中表现出高活性。各种芳基卤化物在绿色条件下与芳基硼酸(Suzuki 交叉偶联反应)和烯烃(Heck 反应)偶联,以高产率到优异的产率提供相应的产品。有趣的是,
