The insertion of arynes into the O-H bond of aliphatic carboxylic acids promoted by sodium carboxylates is described. The reactions led to the formation of aryl carboxylates in good yields with good chemoselectivities under mild conditions.

(Figure Presented) A novel, efficient, and expedient route to biologically and pharmaceutically important o-hydroxyaryl ketones, xanthones, 4-chromanones, and flavones has been developed starting from readily available carboxylic acids and commercially available o-(trimethylsilyl)aryl triflates.
Photochemical Versus Aluminium Chloride-Catalyzed Fries Rearrangement of Aryl Hydrogen Succinates. Synthesis of 2(3H)-Furanones
Fillol, Luis,Martinez-Utrilla, Roberto,Miranda, Miguel A.,Morera, Isabel M.

The photochemical and aluminium chloride-catalyzed Fries rearrangement of a series of aryl hydrogen succinates 3 a-f to the corresponding 4-oxoacids 1 a-f are compared.Both approaches are complementary: the photochemical process is more general and becomes the method of choice for the succinoylation of phenols supporting alkoxy or hydroxy substituents, while the classical rearrangement is superior in the presence of alkyl or halogen substituents.These results are applied to the preparation of the 2(3H)-furanones 2 a-f. - Keywords: Fries rearrangement; Photo-Fries rearrangement; Aryl hydrogen succinates; 4-Oxoacids; 2(3H)-Furanones.
