二氟甲基三氟甲磺酸(HCF2OTf)是一种易于处理、空气稳定且不消耗臭氧的液体试剂,可用于二氟甲基化。在四氯化钛(TiCl4)存在下,它可以通过三氟甲基三甲基硅烷(TMSCF3)和三氟甲磺酸反应来制备 应用: 二氟甲基三氟甲磺酸酯(TfO-CHF2)可作为试剂用于: 二氟甲基化反应。 通过与羟基化的N-基杂环反应制备二氟甲氧基杂环。 在铜和四丁基二氟三苯基硅酸铵(TBAT)的存在下通过用二芳基碘鎓盐处理以合成三氟甲基芳烃。 Difluoromethyl triflate (HCF2OTf) is an easy to handle, air-stable and non-ozone-depleting liquid reagent for difluoromethylation. It can be prepared by reacting trifluoromethyltrimethylsilane (TMSCF3) and triflic acid in the presence of titanium tetrachloride (TiCl4)
