Difluorobenzodioxole is an important functional group found in both pharmaceuticals and agrochemicals. The late-stage introduction of this functional group is challenged by typical fluorination conditions of HF and strong oxidants. Here, we demonstrate that a range of difluorobenzodioxoles can be prepared from catechols in two steps through conversion into thionobenzodioxoles, followed by desulfurative fluorination with silver(I) fluoride. These mild reaction conditions are compatible with a variety of functional groups and enable access to a range of functionalized difluorobenzodioxoles.
Diaryl sulfones through oxidative coupling of catechols and arylsulfinic acids

, p. 1391 - 1396 (2007/10/03)
A simple and efficient method for the synthesis of diaryl sulfones using the coupling reaction of in-situ generated o-benzoquinones, promoted by potassium ferricyanide, and arylsulfinic acids has been developed. High product yields, a short reaction time,
