Conversion of CO2 to value-added chemicals. CO2/H2 Formylation of Amines

The conversion of CO2 to value-added chemicals is highly desirable [1]. The chemical reduction of CO2 using a variety of reductants, such as hydrogen gas, silanes or boranes represent efficient pathways to important chemicals [2]. The formylation of amines, in the presence of CO2 and a reductant, is an important example of chemical transformation leading to important industrial chemical intermediates. The Hydrogen gas-based reduction route (scheme 1) is the cleanest and most atom-economical, however the current catalysts have marked limitations, such as high catalyst loading and/or high temperature and pressure conditions, as well as a limited substrate scope of amines
