Abstract

This paper presents a two-step cascade process for catalytic carbonylations using CO2 and H2. A novel heterogeneous copper catalyst (10Cu@SiO2-PHM) selectively generates CO from CO2 reduction with high selectivity (≥98%) and conversion (27%). This generated CO is directly used in hydroformylation, alkoxycarbonylation, and aminocarbonylation reactions, producing various aldehydes, esters, and amides in high yields and selectivities under ambient conditions. This approach offers a safe and green alternative for continuous syntheses in organic chemistry.
