Abstract Both alkyl and aryl chlorothioformates could readily be obtained from the corresponding alcohols and thiophosgene. These families of compounds were treated with BrF 3 to 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 ...
