  The fluoromethyl ether sevoflurane as a fluoride source in halogen-exchange reactions

  摘要：

  Fluoromethyl 2,2,2-trifluoro-1-(trifluoromethyl) ethyl ether (sevoflurane), fluoromethyl 1,1,2,3,3,3-hexafluoropropyl ether, and fluoromethyl 1,2,2,2-tetrafluoroethyl ether are found to be selective fluoride donors in some halogen-exchange reactions. For example, treatment of a mixture of a polychlorinated substrate and one equivalent of sevoflurane with a catalytic amount of antimony pentachloride gives a monofluorinated product and one equivalent of chloromethyl 2,2,2-trifluoro-1-(trifluoromethyl) ethyl ether as by-product.

  1-Difluoroethyl methyl ethers such as the commercial veterinary anesthetic methoxyflurane (2,2-dichoro-1,1-difluoroethyl methyl ether, 6) decompose in the presence of a catalytic amount of antimony pentachloride. The rate of decomposition is dependent upon the number and position of halogen atoms in the ether: a high degree of halogenation at the methyl group or at the 2-position of the ethyl group makes

  1,1-二氟乙基甲基醚，例如市售的兽用麻醉药甲氧基氟烷（2,2-二氯-1,1-二氟乙基甲基醚，6）在催化量的五氯化锑的存在下分解。分解速率取决于醚中卤素原子的数目和位置：在甲基或乙基的2位上的高度卤化程度使醚不易分解。分解产物是酰基氟和卤代甲烷。五氯化锑的命运被转化为氟氯锑物种，可以原位使用该氟氯锑物种以选择性地氟化多氯化基质。因此，1,2,2,2-四氯-1-氟乙基甲基醚（1利用6作为氟化物源，利用2和6对五价锑物种的稳定性差异，将）干净地转化为麻醉剂化合物2,2,2-三氯-1,1-二氟乙基甲基醚（2）。还证明了由1，1-二氟乙基甲基醚分解得到的酸性氟化物是卤代反应的氟化物来源。
