Indoles and pyrroles occupy a privileged position in pharmaceuticals, material sciences, and natural products.[1] Consequently, methods to synthesize and functionalize these heterocycles are of utmost importance in organic chemistry.[2] Metal-catalyzed cross- coupling is the method most often used for the introduction of (hetero) aryl, vinyl, or acetylene groups to indoles and pyrroles, but it requires premodification of the heterocycle ...
