Both alkyl and aryl chlorothioformates could readily be obtained from the corresponding alcohols and thiophosgene. These families of compounds were treated with BrF3to form the corresponding alkyl and aryl chlorodifluoromethyl ethers in 60–85  yields. The method is suitable for constructing a variety of aliphatic as well as electron-deficient aromatic chlorodifluoromethyl ethers. The reactions proceed under mild conditions and short reaction times. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

Treatment of catechols with thiophosgene provide the corresponding thiodioxoles which upon treatment with bromine trifluoride produce potentially biologically important difluoroaryldioxoles in good to very good yields.
