The direct arylation of furans at a sterically congested C−H bond are accomplished. Although there are many methods for catalytic C−H arylation, direct C−H arylation at bulky reaction sites is one of the most problematic issues in this area. In this study, we found that a PdCl 2 ‐1,2‐bis(dicyclohexylphosphino)ethane (dcype) or PCy 3 and silver salt system enables arylations at a sterically congested C−H bonds to produce “highly congested” and “very congested” triarylfurans.
