PEPPSI protocol

The a-ketone arylation reactions, described in Section 9.2.8, can be applied to the polycondensation of haloarylketones. Thus, Matsubara reported the polymerisation of bromo- or chloro-propiophenone catalysed by mixtures of [Pd(OAc)2] and IPr-HCl or IMes-HCl (3 mol% [Pd]). The former system was more active and the use of excess imidazolium salts resulted in decreased activity, due to the formation of bis-NHC Pd species. A related polymerisation protocol involved Kumada coupling of bromo-aryl Grignards catalysed by a Pd-PEPPSI complex (see Section 9.2.4). ... [Pg.386]
