Palladium-catalyzed selective B(3)–H arylation of <i>o</i>-carboranes with arylboronic acids at room temperature

Abstract

A palladium-catalyzed selective B(3)-H arylation of o-carboranes at room temperature has been developed using readily available arylboronic acids as the aryl source, and the corresponding 3-aryl-o-carboranes were obtained in good to excellent yields. This method provides a powerful synthetic route for constructing polysubstituted o-carborane derivatives.
