The use of well-defined metal nanoparticles for catalysis is an exciting and rapidly growing area. Nanocatalysts have yet been reported as efficient and selective catalysts,1 the most known ones being Pt(Pd)/cinchonidine ones for ethyl pyruvate hydrogenation.2 However, other systems are now emerging.

In our group, the synthesis of metal nanoparticles is performed through an organometallic approach, giving rise to well-dispersed and small nanoparticles with a narrow size distribution.3 In addition they display a controlled surface composition that can be tuned by addition of ligands. This confers them surface coordination chemistry properties4 that can lead to applications in the field of catalysis. Depending on their nature, the ligands may have a high influence on nanoparticles catalytic properties and can induce particular properties.

The synthesis and the characterization of organic ligand stabilized metal nanoparticles will be described as well as interesting catalytic properties in aromatic compounds hydrogenation5 or enantioselective allylic alkylation.6
