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
