Covalently functionalized carbon nanoparticles with a chiral Mn-Salen: a new nanocatalyst for enantioselective epoxidation of alkenes

Abstract

The first nanocatalyst, obtained via “step-by-step” functionalization of CNPs, for enantioselective epoxidation of non-functionalized alkenes is reported here.

Supramolecular Detection of a Nerve Agent Simulant by Fluorescent Zn–Salen Oligomer Receptors

“…Metal–Salen complexes are well known in literature for their use as catalysts [26,27,28,29,30] and supramolecular hosts [31,32,33,34,35,36,37,38], where the Lewis acid metal center is exploited for the recognition of Lewis base species. Furthermore, recently we also demonstrated the high efficiency of metal-Salen complexes as receptors for NA simulants [25,39].…”

Catalytic Degradation of Nerve Agents

“…For this reason, the implementation of molecular catalytic systems into heterogeneous of nanoscopic catalysts could be the goal to obtain efficient decontamination of the environment. As is well known, the possibility to realize solid porous surface/support containing a catalytic specie leads to an increase of the activity/reactivity, also obtaining a reusable device [119][120][121]. Scientific progresses in the field of surfaces and nanoparticles functionalization improves the possibility of enhancing the results actually obtained with regard to NAs degradation.…”

Catalysis with carbon nanoparticles

“…Recently, our research group developed a "new derivatization protocol" of CNPs based on the covalent functionalization of the external shell, leading to a stable catalyst. 21 In particular, we anchored a chiral Mn-salen catalyst onto carbon nanoparticles for the enantioselective epoxidation of some selected alkenes (dihydronaphtalene, CN-chromene and cis-b-ethylstyrene, Scheme 5). Morphology of the nanocatalyst has been elucidated by XPS, SEM and TEM analysis.…”
