Abstract (EN): Manganese(III) salen complexes bearing hydroxyl groups on the aldehyde moiety were grafted onto the surface of an air oxidised activated carbon. The resulting carbon materials were characterised by elemental analysis, X-ray photoelectron spectroscopy and N-2 adsorption at 77 K. The catalytic activity of the novel manganese(III) salen based materials was tested in the epoxidation of styrene in acetonitrile, using iodosylbenzene as oxygen source, and compared with the corresponding homogeneous phase data. The heterogenised catalysts are chemoselective towards the styrene epoxide as their homogeneous counterparts, are resistant to leaching and can be re-used without loss of their catalytic activity.
