A simple and efficientRh-phosphinitecomplexcatalyst was studied for the selective hydroformylation of various olefins. The influence of various reaction parameters including the effect of temperature, pressure, catalyst loading, time, and solvents was studied. The protocol was also applied for the synthesis of various acetals via tandem hydroformylation–acetalization of olefins in alcohols as solvents

Hydroformylation, also known as the “oxo” process, is a major industrial process that employs rhodium or cobalt catalysts in solution; therefore the solvent of this process is a critical issue for its sustainability. Although several innovative solutions have been proposed recently, traditional fossil-derived solvents dominate the scenario for this reaction. In this paper, we studied a series of solvents

Although zeolite-encapsulated [Rh(CO)x(PR3)y](PR3= PEt3, PEt2Ph, PPrn3 or PPh3) give similar chemoselectivities in the hydrocarbonylation of hex-1-ene relative to their homogeneous analogues, the linear : branched ratio can be increased by as much as 10 times.
The Rh/BINAPa and ZSM-35(10) co-catalyzed tandem hydroformylation–acetalization of olefins is developed to afford the corresponding acetals with high regioselectivities and excellent catalytic activities.
