摘要

An overview of the recent bibliography concerning the N-heterocyclic carbene (NHC)-mediated activation of tetravalent silicon compounds is presented. Diverse reactions are discussed, such as the NHC-mediated addition of silyl pronucleophiles to a variety of electrophiles, NHC-promoted organic and inorganic polymerisation and the reduction of CO_2 by hydrosilanes as facilitated by NHCs. The review concludes with a discussion of the current knowledge regarding the role of Lewis acid-base NHC-Si interactions in the mechanistic course of these reactions. Very versatile: N-Heterocyclic carbenes (NHCs) have been reported as catalysts or initiators of a variety of organic transformations that involve silicon compounds, such as the addition of silyl pronucleophiles to a variety of electrophiles, organic and inorganic polymerisation and the reduction of CO_2 by hydrosilanes (see scheme). A summary of these developments and a discussion of the current knowledge regarding the mechanistic course of these reactions is presented.
