芳烃的非金属催化氢化代表了一种可持续且环境友好的环己烷衍生物合成方法。在此,我们报告了硼离子催化剂系统的开发,该系统可以氢化多种单环芳烃。此外,这种无金属催化系统允许通过改变反应条件选择性地部分或完全氢化萘和蒽。我们的机理研究表明,硼芳烃介导的 H 2分裂发生在限速步骤之前,生成的中性硼烷和质子化芳烃之间的氢化物转移可能是催化过程中的限速步骤。
Polysilane-Immobilized Rh–Pt Bimetallic Nanoparticles as Powerful Arene Hydrogenation Catalysts: Synthesis, Reactions under Batch and Flow Conditions and Reaction Mechanism
Hydrogenation of arenes is an important reaction not only for hydrogen storage and transport but also for the synthesis of functional molecules such as pharmaceuticals and biologically active compounds. Here, we describe the development of heterogeneous Rh-Pt bimetallic nanoparticlecatalysts for the hydrogenation of arenes with inexpensive polysilane as support. The catalysts could be used in both

the hydrogenation of benzene and benzene derivatives to give the corresponding cyclohexanes under biphasic conditions. The catalytic activity of 2 depends markedly on the substrate, an extremely high activity being observed for ethylbenzene. The cationic species present in the catalytic mixture of the ethylbenzene hydrogenation could be isolated as the tetrafluoroborate salt and characterised as the
