One-Pot Palladium(II)-Catalyzed Synthesis of Fluorenones via Decarboxylative Cyclization.

A one-pot palladium-catalyzed synthesis of fluoronones via decarboxylative cyclization is reported. This protocol offers good yields and tolerates a broad range of functional groups. Based on the extensive experimental data, we propose a plausible decarboxylative insertion mechanism. [ABSTRACT FROM AUTHOR]
