本文报道了一种绿色可循环利用的壳聚糖负载铜催化剂,该催化剂能够在室温下催化α,β-不饱和受体的硼化反应。广泛的底物范围,包括查耳酮衍生物,酯和腈已被探索。在所有情况下,以良好至优异的产率获得所需产物。值得注意的是,这种壳聚糖负载的催化剂可以回收和重复使用5次,没有任何显着的反应性下降。
We herein report a green and recyclable chitosan supported copper catalyst which is capable of catalyzing the borylation of α,β-unsaturated acceptors in water at room temperature. A broad substrate scope including chalcone derivatives, esters and nitriles have been explored. In all the cases, desired products were obtained in good to excellent yields. Remarkably, this chitosan supported catalyst could be recovered and reused for five times without any significant decrease of reactivity.
