RhCl(CO)(TFFMS)2 y RhCl(TFF)3 inmovilizados sobre MCM-48 funcionalizado y su estudio catalítico en reacciones de hidroformilación de 1-hexeno

Two new hydrids catalyst were synthetized (I) from chlorocarbonyl-bis-(diphenyl(m-sulphonate of sodium- phenyl)phosphine) rhodium(I) and (II) from chlorotris-triphenylphosphine rhodium(I) supported on functionalized MCM-48 using post-synthesis methods with (3-(2-aminoetilamino)propil) and trimetoxisilano as anchoring and passivation ligands, respectively. The catalyst were characterized by infrared spectroscopy (IR), mass spectrometry (MS), thermogravimetric analysis (TGA), nitrogen adsorption-desorption and scanning electron microscopy and energy dispersive X-ray analysis (SEM/EDX). Catalytic test were performed in hydroformylation reactions and the reactions parameters were optimized (time, temperature, substrate/catalyst ratio and syngas pressure H2/CO). Supported complexes showed high conversion rates and were reused up to five times without apparent loss of catalytic activity.
