description A method of preparing vicinal difluoro aromatic compounds in high yield from hydroxy aromatic compounds and a method of preparing intermediates thereof. The hydroxy aromatic compound can be a mono-, bi- or tricyclic aromatic in which the rings are separate or fused. One or more of the rings can contain heteroatoms, such as oxygen, nitrogen, or sulfur, and can contain one or more substitutions, in addition to the hydroxy substitution.
