Continuous Gas-Phase Hydroformylation of Propene with CO₂ Using SILP Catalysts

Hydroformylation is an important process for the synthesis of aldehydes and alcohols in the chemical industry. Although this process uses toxic CO as one of the reactants, some types of Ru complex catalysts have been known to replace CO with CO2 as a reactant in hydroformylation. Herein, we report the continuous hydroformylation of propene with CO2, heterogeneously catalyzed by supported Ru complexes on silica using ionic liquids [i.e.,...
