The reduction of nitro compounds to the corresponding amines is one of the most utilized catalytic processes in the fine and bulk chemical industry. The latest development of catalysts with cheap metals like Fe, Co, Ni, and Cu has led to their tremendous achievements over the last years prompting their greater application as “standard” catalysts. In this review, we will comprehensively discuss the use of homogeneous and heterogeneous catalysts based on non-noble 3d-metals for the reduction of nitro compounds using various reductants. The different systems will be revised considering both the catalytic performances and synthetic aspects highlighting also their advantages and disadvantages.

使用3d-非贵金属催化剂还原硝基化合物

将硝基化合物还原为相应的胺是精细和批量化学工业中最常用的催化方法之一。近年来，使用廉价金属（如Fe，Co，Ni和Cu）制成的催化剂的最新发展使其取得了巨大成就，促使其更广泛地用作“标准”催化剂。在这篇综述中，我们将全面讨论基于非贵金属3d金属的均相和非均相催化剂用于使用各种还原剂还原硝基化合物的方法。将考虑催化性能和合成方面，同时突出其优点和缺点，对不同的系统进行修订。
