Abstract
![]()
In this work, we
demonstrate how allylative dearomatization of
benzyl chlorides can provide direct access to a variety of semibenzenes.
These scaffolds behave as highly reactive nucleophiles in the presence
of carbocations. In addition, semibenzenes are susceptible to intramolecular
rearrangements rendering a broad scope of functionalized arenes. An
analysis of this new reactivity is reported, as well as the rationale
behind the observed intramolecular reorganizations.
