Rhodium‐Catalyzed Allylation of Trisubstituted Alkenes with gem ‐Difluorinated Cyclopropanes: Access to All‐Carbon Tetrasubstituted Alkenes

A rhodium‐catalyzed allylation of trisubstituted alkenes with gem‐ difluorinated cyclopropanes ( gem ‐DFCPs) has been developed to access all‐carbon tetrasubstituted olefins. This transformation exhibits robust functional group compatibility and utilizes gem ‐DFCPs as versatile fluorine‐containing building blocks, delivering a diverse range of all‐carbon tetrasubstituted olefins in moderate to good yields. The synthetic utility of this strategy is further highlighted by its applicability to late‐stage functionalization.
