Title

Selectivity in the Rearrangements of Oxonium Ylides

Abstract

Oxonium ylides were formed via an intramolecular reaction between a series of dioxalanes and metallocarbenes. The substitution patterns present in the ketals greatly affect the rearrangements of the oxonium ylides. It was also demonstrated that electron-deficient copper (II) species are superior catalysts for these systems.
