For fixed syngas composition and partial pressure, the H2/CO ratio in CO2-expanded liquids (CXLs) is increased significantly with increasing CO2 pressure. For Rh/TPP catalyzed 1-octene hydroformylation in CXLs, the higher H2/CO ratios result in enhanced TOFs and exceptional regio-selectivity. These findings have broad fundamental and practical implications for developing greener hydroformylations.
