Alpha-Hydroxyaryl ketones such as 2-hydroxypropiophenone and 1-(2,4-difluorophenyl)-2-hydroxy-1-propanone, the key intermediates in the preparation of antifungal agents, decompose into oxidized, rearranged, and condensed products. These products were isolated and characterized. The possible mechanisms for the formation of the products are discussed.

A short, high-yielding synthesis of differentially substituted resorcinol derivatives has been developed that utilizes 1,3-difluorobenzene as the starting material and employs sequential nucleophilic aromatic substitution (S(N)Ar) reactions to generate desymmetrized products. The scope and limitations of the second S(N)Ar reaction
