Both alkyl and aryl chlorothioformates could readily be obtained from the corresponding alcohols and thiophosgene. These families of compounds were treated with BrF3 to form the corresponding alkyl and arylchlorodifluoromethylethers in 60–85 % yields. The method is suitable for constructing a variety of aliphatic as well as electron-deficient aromatic chlorodifluoromethylethers. The reactions proceed
