Abstract
Strained alcohols have featured prominently in a wide array of transition-metal-catalyzed
cross-coupling reactions, but methods involving cyclopropanols have only been developed
relatively recently. In this account, we describe our group’s work in this area, and
we provide a concise summary of other palladium-catalyzed methods for C–C bond-forming
reactions using cyclopropanols.
