Abstract

Abstract : The first nanocatalyst, obtained via "step-by-step" functionalization of CNPs, for enantioselective epoxidation of non-functionalized alkenes is reported here. Abstract : A new protocol to obtain carbon nanoparticles (CNPs) covalently functionalized with a chiral Mn-Salen catalyst is described here. The new nanocatalyst (CNPs-Mn-Salen ) was tested in the enantioselective epoxidation of some representative alkenes (CN-chromene, 1, 2-dihydronaphthalene and cis -β-ethyl styrene), obtaining better enantiomeric excess values than that of the catalyst single molecule, highlighting the role of the nanostructure in the enantioselectivity.
