title: Synthesis of fluorenones through rhodium-catalyzed intramolecular acylation of biarylcarboxylic acids.
abstract: An efficient approach to the synthesis of fluorenones via the rhodium-catalyzed intramolecular acylation of biarylcarboxylic acids was developed. Using this procedure, fluorenones with various substituents can be synthesized in good to high yields. This work marks the first recorded use of catalytic intramolecular acylation to synthesize fluorenones.
