Abstract Achiral and chiral cationic palladium catalysts, modified with atropisomeric PˆN ligands with different steric and electronic properties, can efficiently produce poly(styrene‐ alt ‐CO) with essentially complete regioregularity and variable tacticity, depending on the ligand geometry; the electronic effect on catalytic activity depends on the geometry of the ligand.
