Selective reduction of carbon dioxide to bis(silyl)acetal catalyzed by a PBP-supported nickel complex

The selective reduction of CO 2 to the formaldehyde level remains an important challenge and to date only a few catalysts have been developed for this reaction. Herein, we report an efficient catalyst that consists of a bis(phosphino)boryl nickel hydride complex in combination with B(C 6 F 5 ) 3 , for the highly selective hydrosilation of CO 2 to bis(silyl)acetal derivatives. The selective reduction of CO 2 to the formaldehyde level remains an important challenge and to date only a few catalysts have been developed for this reaction.
