Biologically interesting fluorenone, xanthone and anthrone derivatives have been prepared via an intramolecular oxidative acylation process. This novel direct acylation reaction proceeded without the aid of any transition metals, acids or bases, and uses a catalytic amount of a quaternary ammonium salt in the presence of a persulfate oxidant. Initial mechanistic studies have been carried out to elucidate the reaction pathway. The Royal Society of Chemistry 2013.

A decarboxylative radical cyclization reaction has been developed for the synthesis of fluorenones. The reaction uses Ag(I)/K2S 2O8 to oxidatively decarboxylate an aroylbenzoic acid to an aryl radical, which undergoes cyclization to afford fluorenone products in good yield.
