This minireview covers recent progress in the functionalization of C(sp²)−Si bonds by intramolecular activation by alkoxides. Such processes involve the formation of a cyclic hypervalent silicon intermediate that allows carbon‐to‐oxygen migration of the organosilyl group and thus the formation of a carbanionic species poised to undergo electrophilic substitution. The C(sp²)−Si bond cleavage can be “endocyclic” (Brook rearrangement) or “exocyclic”.

通过醇内分子活化的C（sp2）-Si键功能化

这份小型综述涵盖了通过醇盐分子内活化在C（sp ²）-Si键功能化方面的最新进展。此类过程涉及形成环状高价硅中间体，该中间体允许有机甲硅烷基的碳-氧迁移，从而形成准备进行亲电取代的碳负离子物质。C（sp ²）-Si键断裂可以是“环内的”（布鲁克重排）或“环外的”。
