Ligand-Free, Cu- and Fe-Catalyzed Selective Ring-Opening Arylations of Benzoxazoles with Aryl Iodides

PhI(OAc)2/Pd(OAc)2 promoted the formation of 8-hydroxyquinoline derivatives from benzoxazoles and alcohols

A PhI(OAc)₂/Pd(OAc)₂ system that synergistically promotes the formation of 8-hydroxyquinoline derivatives from benzoxazoles and alcohols has been developed. The reaction proceeded smoothly with a range of benzoxazoles and alcohols to give the corresponding 8-hydroxyquinoline derivatives in moderate yields.
