A new protocol to obtain Carbon Nanoparticles (CNPs) covalently functionalized with a chiral Mn-salen catalyst is here described. The new nanocatalyst (CNPs-Mn-Salen) was tested in the enantioselective epoxidation of some representative alkenes (CN-chromene, 1,2-dihydronapthalene and cis-β-ethyl styrene), obtaining better enantiomeric excess value respect to the catalyst single molecule, highlighting the role of the nanostructure in the enantioselectivity.
