Abstract

Abstract The palladium-catalyzed CH activation and arylation of N-methylpyrrole and N- phenylpyrrole allowed a convenient synthesis of diarylpyrroles. The reactions were performed by using tetrabutylammonium acetate as an ionic solvent, which allowed for the application of a ligand-free catalytic system by using simple palladium salts or polyvinylpyrrolidone-stabilized palladium nanoparticles as the catalyst.
