Abstract
Facile polymerization reaction conditions were developed for synthesizing conjugated polymers via direct arylation and the Buchwald-Hartwig aryl amination reactions under aerobic conditions. Refluxing the reaction solvent and using XPhos Pd G2 as a precatalyst proved to be a tolerant polymerization protocol for direct arylation polycondensation, which eliminates the need for an inert gas atmosphere and can successfully proceed using commercially available, reagent-grade N,N-dimethylformamide (DMF) as the solvent. This strategy was also successfully applied to the Buchwald-Hartwig aryl amination polycondensation in toluene, which provided poly(triarylamine)s in air.
