Abstract
The Brook rearrangement is a valuable synthetic tool that facilitates the controlled
construction of complex molecules. Conventionally, it generates carbanion intermediates
utilized in subsequent functionalization reactions. In this review, we will explore
recent advancements in the Brook rearrangement that extend beyond the traditional
functionalization reactions. Specifically, we will highlight its involvement in unusual
bond cleavage, annulation reactions, and dearomatization efforts. The novelty of this
rearrangement is underscored by showcasing its most recent applications.
