A short, high-yielding synthesis of differentially substituted resorcinol derivatives has been developed that utilizes 1,3difluorobenzene as the starting material and employs sequential nucleophilic aromatic substitution (SNAr) reactions to generate desymmetrized products. The scope and limitations of the second SNAr reaction on the deactivated 1-alkoxy-3-fluorobenzene intermediates have been investigated. This methodology has also been employed in the synthesis of desymmetrized catechol derivatives from 1,2difluorobenzene.
