Homogeneous catalytic reduction of CO2 with hydrosilanes

Catalytic CO2 hydrosilylation is a thermodynamically favored chemical process that could be potentially applied to large-scale transformations of this greenhouse gas. During the last decade, there have been an increasing number of experimental studies regarding metal-catalyzed CO2 hydrosilylation processes. The first examples of catalytic systems used for CO2 hydrosilylation employed late transition metals such as ruthenium and iridium. Presently, there are several examples of other catalysts, including transition metal species acting alone or together with B(C6F5)(3), as well as metal-free frustrated Lewis pairs (FLPs) and organocatalysts which are able to perform this reaction.
