The palladium‐catalyzed CHactivation 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

palladium‐catalysed direct polyarylation of 1‐methylpyrrole and 1‐phenylpyrrole was studied. As the C2 and C5 positions of pyrroles are more reactive for CH bond functionalisation than the C3 and C4 positions, the formation of 2,5‐diarylpyrroles was found to proceed selectively in the presence of 3 equiv. of a variety of arylbromides. The sequential C2 arylation followed by C5arylation to prepare non‐symmetrically
