RhCl(CO)(PPh3)2 was anchored to diphenylphosphinopropyl-modified (–PrPPh2) mesoporous silicate MCM-41. Infrared spectroscopy was applied to monitor the multi-step assemble of the complex by assigning critical absorptions. The prepared catalyst was employed in 1-octene hydroformylation and showed high conversion of substrate as well as high selectivity of nonyl aldeydes (>97%) along with several stable catalyst cycles. Rhodium leaching in the reaction liquids was determined by mass spectroscopy, which was found extremely low. The catalyst showed higher activity and lower metal loss than the analogue by nano SiO2 as support, probably as a result of the confining of molecular sieves with ordered pores.
