A robust method of roomtemperature direct arylation for benzofuran is reported. This discovery allows for mild arylation by commercially available aryl iodides with complete C-2 regioselectivity and tolerates a range of functional groups, including heat sensitive groups. Mechanistically, a Heck-type oxyarylation product from a direct arylation process is reported as a key piece of evidence for a carbopalladation
A new method for synthesis of benzofurans and naphthofurans from 2-hydroxystilbene derivatives via an intermolecular cyclization is reported in this study with up to 94% isolated yield.
