Abstract
A regioselective oxidative allylic C(sp3)-H arylation of readily available unactivated terminal and internal olefins with a broad range of heteroaryl boronic acids is catalyzed by cheap, abundant, and nontoxic Cu2O. This method does not require traditional coupling partners with preinstalled leaving groups at the allylic position, thus offering an alternative method to allylic arylation.
