readily available aromatic ketones and gem-difluoroalkenes under oxidant-free, acid-free and metal-free conditions for the synthesis of phenanthrenes. Carbonyl-olefin metathesis and dehydrogenative cyclization proceed in a one-pot reaction. The reactions show broad substrate scope and wide functional group tolerance.
