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

 Journal of Polymer Science Part A: Polymer Chemistry

The use of an air and moisture stable, commercially available (N-heterocyclic carbene)-Pd complex as precatalyst allows for the Buchwald-Hartwig polyamination of aryl chlorides with primary amines. Different approaches for the end-capping of the polymers have also been evaluated. The step growth polymerizations exhibit molecular weight from 2000 to 15000 Da and PDI from 1.1 (2000 Da) to 3.0.
