(N-heterocyclic carbene)-Pd catalyzed synthesis of poly(triarylamine)s by Buchwald-Hartwig coupling of aryl chlorides

The use of an air and moisture stable, commercially available (N‐heterocyclic carbene)‐Pd complex as precatalyst allows for the unprecedented Buchwald‐Hartwig polyamination of aryl chlorides with primary amines. Different approaches for the end‐capping of the polymers have also been evaluated....
