Abstract

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