Arene hydrogenation was greatly accelerated by a cooperative catalytic system that consisted of heterogeneous Rh-Pt nanoparticles and Lewis acids. Remarkably, particularly challenging substrates that contained strong electron-donating groups and sterically hindered substituents could be smoothly hydrogenated.

Piperidines are one of the most widely used building blocks in the synthesis of pharmaceutical and agrochemical compounds. The hydrogenation of pyridines is a convenient method to synthesise such compounds as it only requires reactant, catalyst, and a hydrogen source. However, this reaction still remains difficult for the reduction of functionalised and multi-substituted pyridines. Here we report the
哌啶是药物和农化化合物合成中使用最广泛的结构单元之一。吡啶的氢化是合成此类化合物的便捷方法,因为它只需要反应物、催化剂和氢源。然而,该反应对于官能化和多取代吡啶的还原仍然很困难。在这里,我们报道了使用稳定的市售铑化合物Rh 2 O 3来还原各种未保护的吡啶。该反应条件温和,底物范围广,具有实用价值。
