Abstract

We describe the development of a new catalyst system for carbonyl-olefin ring-closing metathesis reactions that relies on Lewis acidic superelectrophiles and significantly expands the current scope of this transformation to medium-sized rings.
Importantly, these superelectrophiles are shown to promote carbonyl-olefin metathesis via a distinct and unprecedented mechanism.

Keywords

carbonyl-olefin metathesis, Lewis acid superelectrophiles
