Fe/ppm Pd nanoparticles and PEG‐containing designer surfactants, a facile and selective reduction of nitro‐containing aromatics and heteroaromatics can be effected in water at room temperature in the presence of NaBH4. This new nanotechnology involves low catalyst loadings, is highly chemoselective, and tolerates a wide variety of functional groups. The process, which includes recycling of the entire
由于无配体的Fe / ppm Pd纳米颗粒与含PEG的设计剂表面活性剂之间具有独特的协同作用,因此在室温下水中存在NaBH 4的情况下,可以轻松,选择性地还原含硝基的芳族化合物和杂芳族化合物。这项新的纳米技术涉及低催化剂负载量,高度化学选择性,并能耐受多种官能团。该过程包括整个水性介质的循环利用,它为减少有价值的含硝基化合物提供了一种通用的,对环境负责的,尤其是安全的方法。
