Candida parapsilosis ATCC 7330 supported gold nanoparticles (CpGNP), prepared by a simple and green method can selectively reduce nitroarenes and substituted nitroarenes with different functional groups like halides (–F, –Cl, –Br), olefins, esters and nitriles using sodium borohydride. The product aryl amines which are useful for the preparation of pharmaceuticals, polymers and agrochemicals were obtained in good yields (up to >95%) using CpGNP catalyst under mild conditions. The catalyst showed high recyclability (≥10 cycles) and is a robust free flowing powder, stored and used after eight months without any loss in catalytic activity.

酵母负载的金纳米颗粒：合成商业上重要的芳基胺的有效催化剂

通过简单，绿色的方法制备的假丝酵母假单胞菌ATCC 7330支持的金纳米粒子（CpGNP）可以使用硼氢化钠选择性还原具有不同官能团（例如卤化物（-F，-Cl，-Br），烯烃，酯和腈）的硝基芳烃和取代的硝基芳烃。使用CpGNP催化剂，在温和的条件下，以良好的收率（高达95％以上）获得了用于制备药物，聚合物和农用化学品的芳基胺产物。该催化剂显示出很高的可回收性（≥10个循环），并且是一种坚固的自由流动性粉末，八个月后可以储存和使用，而催化活性没有任何损失。
