Newrhodium complexes of formula [RhCl(COD)L], [RhCl(CO)2L], [Rh(PPh3)2L] and the corresponding cationic ones, where L = 2-(3-triethoxysilylpropyl)aminocarbonyl-pyrrolidine, have been covalently bound to silica and ultrastable Y-zeolite containing supermicropores. The complexes anchored on the zeolite show a higher activity for alkene hydrogenation than the free complexes in homogeneous medium, the
