Abstract

Pd(II)-chitosan composite nanofibres of 62 ± 9 nm diameter are efficient catalysts for Heck cross-coupling reactions. Using a model reaction of iodo-benzene and n-butyl acrylate, we demonstrate that this material can be used as a recyclable catalytic support with a very low loading of palladium (0.17 mol% Pd).

摘要

直径为 62±9nm 的 Pd(II)-壳聚糖复合纳米纤维是 Heck 交叉偶联反应的高效催化剂。通过碘苯和丙烯酸丁酯的模型反应,我们证明这种材料可以作为一种可回收的催化载体,负载量非常低的钯(0.17mol%Pd)。
