Homogeneous Catalytic Reduction of CO2 with Silicon-Hydrides, State of the Art

During recent years, the catalytic transformation of CO2 using silicon-hydrides as reductants has emerged as a promising methodology that allows the selective reduction of CO2 to the formate, formaldehyde, methoxide or methane level under mild reaction conditions. Moreover, some catalysts have been employed for the formylation and/or methylation of the N-H bonds of secondary and/or primary amines by their reaction with CO2 and hydrosilanes. This work summarizes the different catalytic systems that have shown to be efficient for the above-mentioned reactions. Furthermore, a brief description of the reactions performance and the conditions employed in each case is included.
