Abstract
Methods of metal-catalysed polymerisation are described using a metal catalyst of formula (III): wherein Rin each occurrence is independently selected from Calkyl and aryl that may be unsubstituted or substituted with one or more substituents; y is 0 or 2; and Zis an anion. Methods described include Buchwald-type and Suzuki-type polymerisation.
