deprotonation with n-BuLi on the organometallic intermediate, and trapping with electrophiles including alkyl and acyl halides and aldehydes. The electrophilic addition step occurred at a stabilized α-silyl carbanion center without affecting the near transition metal residue. In the case of aldehydes, the Peterson alkenation reaction took place on the transition metal complex in a highly stereoselective way

A visible light driven nickel carbonylation catalyst has been develop. This offers a method for carbonylative coupling reactions with an earth abundant metal at ambient temperature for the conversion of alkyl halides into synthetically versatile acid chlorides. The acid chlorides can then be transformed into an array of challenging ester, thioester and amide products.

α-(Silyl)acetates are a class of stable and versatile organosilicon compounds wherein the inherent diversity of silicon can be exploited to unlock reactivity through masked carbanions, carbon nucleophiles, carbon-centered radical intermediates, and silicon electrophiles. Hence the developing of new methodology for their preparation is important and attractive. Herein, we developed an efficient method
