Small rhodium nanoparticles (ca. 3.5 nm) were prepared by the decomposition of an organometallic precursor under hydrogen pressure in glycerol using 1‐thioglycerol as stabilizer. Full characterization in the solid state [HR‐TEM, EDX, XPS] showed a fcc structure for the Rh⁰/Rh^I nanoparticles capped with thiolate ligand. Reduction of different functionalities, including nitro groups and imines, was applied to tandem reductive amination of aldehydes with primary and secondary amines, and to the synthesis of N‐substituted anilines from nitrobenzene. In addition, thiolate‐capped RhNPs could be recovered and reused up to 5 runs without loss of activity nor selectivity.

双相介质中硫醇稳定的铑纳米粒子在多步反应中作为催化剂

通过使用1-硫代甘油作为稳定剂，在氢气中于甘油中将有机金属前体分解，可以制备出小的铑纳米颗粒（约3.5 nm）。固态[HR-TEM，EDX，XPS]的完整表征表明，Rh ⁰ / Rh ^I纳米粒子被硫醇盐配体封端时，其fcc结构。减少不同的官能团（包括硝基和亚胺）可用于醛与伯胺和仲胺的串联还原胺化反应，以及从硝基苯合成N取代苯胺的过程。此外，硫醇盐封端的RhNPs可以回收并重复使用多达5次，而不会损失活性或选择性。
