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
