work up process, the product was easily separated from the reagent. Thus, the reaction would be a practical preparation method for polyfluorinated esters. Trifluoromethyl chlorodifluoroacetate was obtained by the reaction of 1,2-dichlorotrifluoroethyltrifluoromethyl ether with fuming sulfuric acid in 49% yield.
该研究的重点是使用多孔氟化铝(PAF)或MF n / PAF将氯氟醚脱氟为相应的酯。在后处理过程中,产品很容易与试剂分离。因此,该反应将是用于多氟化酯的实用制备方法。通过使1,2-二氯三氟乙基三氟甲基醚与发烟硫酸反应,以49%的收率得到三氟氯二氟乙酸甲酯。
