Taking a new turn: An asymmetricSuzuki–Miyauracoupling of 1‐bromo‐2‐naphthalenephosphonic esters with o‐methyl‐substituted phenylboronic acids proceeds with high enantioselectivity in the presence of high‐molecular‐weight helicallychiral polyquinoxaline‐based phosphines (PQXphos) bearing pendant diarylphosphino groups.
