Expanding the Scope of Palladium-Catalyzed B – N Cross- Coupling Chemistry in Carboranes

Abstract

Here we show that azide, sulfonamide, cyanate, and phosphoramidate nucleophiles can be straightforwardly cross-coupled onto the B(9) vertices of the o- and m-carborane core from readily accessible precursors without significant deboronation by-products, laying the groundwork for further study into the utility and properties of these new B-aminated carborane species.
