Homogeneous catalytic reduction of CO2 with hydrosilanes

Abstract

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.
