Abstract

The combination of Me₃SiO^- and Bu₄N⁺ serves as a general activator of organotrimethylsilanes for addition reactions. A broad scope of bench-stable trimethylsilanes (including acetate, allyl, propargyl, benzyl, dithiane, heteroaryl, and aryl derivatives) can be used as carbanion equivalents for synthesis. Reactions are achieved at rt without the requirement of specialized precautions that are commonplace for other organometallics.
