摘要
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 PdCl2-1,2-bis(dicyclohexylphosphino)ethane (dcype) or PCy3 and silver salt system enables arylations at a sterically congested C-H bonds to produce highly congested and very congested triarylfurans.
