Highlights
- Synthesis and characterisation of small RhNPs stabilised by N-heterocyclic carbenes.
- Evidence of the location of the ligands on the faces, edges and apexes of the NPs.
- Hydrogenation of aromatic ketones, phenols and N-heteroaromatic substrates.
- Tuning of the selectivity as a function of the reaction conditions.
- Full reduction of quinoline under mild conditions with total selectivity.
13C{1H} CP-MAS spectra of (a) L, (b) Rh0.4, (c) Rh0.4 + CO and (d) 13C-Rh0.4.
