title = "Dibenzofuran Synthesis: Decarbonylative Intramolecular C−H Arylation of Aromatic Esters",
abstract = "A method to provide dibenzofurans through decarbonylative C−H arylation is described. Diaryl ethers bearing an ester functional group, which can be readily prepared by a SNAr reaction, underwent intramolecular C−H arylation in the presence of a palladium catalyst to afford the corresponding dibenzofurans. Electron-rich bis(dialkylphosphine)s such as dcype were critical as the ligand, otherwise the reactions did not proceed at all. This is the first example of C−H arylation of aromatic esters with simple arenes utilized in intramolecular fashion.",
