Abstract
Rhodium-catalyzed deoxygenations and borylations of ketones with B2pin2 provide alkenes, vinylboronates, and vinyldiboronates. These reactions offer mild reaction conditions, a broad substrate scope, and excellent functional-group compatibility. Mechanistic studies support that the ketones initially undergo a Rh-catalyzed deoxygenation to give alkenes via boron enolate intermediates.
