Objectives
Develop an innovative catalytic tool based on well-defined metal nanoparticles (NPs)[1] confined inside core-shell polymeric nanoreactors [2]. Internal anchoring groups (carboxylates in the shell, various phosphines, amines, etc. in the core) are expected to improve the selective introduction of organometallic precursors and to control both the growth and localisation of the NPs. Higher activity and selectivity can result from the confinement of the particles inside the nanoreactors that will protect them.
Expected Results
Combine the advantages of the aqueous biphasic protocol for easy catalyst recovery and recycling and the specific catalytic performance of metal nanoparticles. Site confinement of different catalysts for one-pot tandem applications. Main reactions of interest: aromatic hydrogenation, hydroformylation, Suzuki coupling, etc. with constant activity for at least 5 recycles and leaching < 1 ppm per cycle.
