Starting from the readily available substrates, an efficient method for the synthesis of fluorenone derivatives has been developed.

processes can be greatly enhanced when the possibility exists for one to selectively diverge from a common intermediate. In preliminary studies the dual reactivity of aryl–palladiumintermediates is exploited. A diverse array of fluorene and phenanthrenederivatives were synthesized in a rapid and efficient manner (see scheme).
