Аннотация: The design of novel active heterogeneous hydroformylation catalysts that are resistant to active metal leaching is an important task. The solution is typically the use of functionalized supports, most often containing an organophosphorus complexing group. The lability of such materials (a tendency to oxidation and hydrolysis) necessitates the search for alternative solutions. One such solution is the use of nitrogen-containing materials that are also capable of interacting with metals active in hydroformylation, particularly rhodium. In this study, a series of nitrogen-containing organosilicon materials with varying organic content were synthesized with urea as a nitrogen source. These materials were used to obtain hydroformylation catalysts consisting of rhodium nanoparticles. The composite supports and catalysts were characterized by a combination of physicochemical analysis methods (ICP-AES, FT-IR, XPS, SEM, TEM, XRD, and low-temperature nitrogen sorption). The catalyst was found to be active in hydroformylation of the model substrate (1-octene), as well as a range of other linear olefins, and also cyclohexene and styrene. The highest activity value (913 h–1) was achieved using a catalyst based on the (UF)2Si support synthesized at a urea:formaldehyde:TEOS molar ratio of 2:4:1. The synthesized catalyst can be reused repeatedly without significant decrease in activity.
