A new series of nanostructured platinum catalysts able to catalyze the selective reduction of nitroarenes has been developed. The materials, made of organosilica physically doped with nanostructured platinum(0), are stable and efficient. Reactions in general proceed with high yield and often go to completion, while the catalysts can be reused in further reaction runs. This establishes a new class of
已经开发了一系列能够催化硝基芳烃选择性还原的纳米结构铂催化剂。该材料由物理掺杂有纳米结构的Platinum(0)的有机二氧化硅制成,稳定且高效。通常,反应以高收率进行并且经常完成,而催化剂可以在以后的反应运行中重复使用。这为合成有机化学建立了新的一类相关的固体催化剂,称为Silia Cat铂水凝胶。
