我们在这里描述的制备铜纳米粒子稳定的壳聚糖/聚(乙烯醇)复合膜。该材料在温和条件下可催化α,β-不饱和受体的硼化反应。相应的有机硼化合物以及它们转化的β-羟基产物都以良好至优异的产率获得。值得注意的是,这种铜纳米颗粒催化剂可以很容易地循环使用八次,并保持催化活性。这种新开发的方法为有机硼化合物的合成和铜纳米颗粒的应用提供了一种有效和可持续的途径。
We describe here the preparation of copper nanoparticles stabilized on a chitosan/poly (vinyl alcohol) composite film. This material could catalyze the borylation of α,β-unsaturated acceptors in aqueous media under mild conditions. The corresponding organoboron compounds as well as their converted β-hydroxyl products were all obtained in good to excellent yields. It is noteworthy that this catalyst of copper nanoparticles can be easily recycled eight times and remained catalytically reactive. This newly developed methodology provides an efficient and sustainable pathway for the synthesis of organoboron compounds and application of copper nanoparticles.
