Efficient synthesis of fluoren-9-ones by the palladium-catalyzed annulation of arynes by 2-haloarenecarboxaldehydes
(Chemical Equation Presented) Fluoren-9-ones and derivatives are readily prepared in good yields by the annulation of in situ generated arynes by 2-haloarenecarboxaldehydes in the presence of a palladium catalyst.
