F is added to hydrofluoric acid so as to form a thick solution (hydrogen bonded complex), and the solution is directly supplied to a liquid phase reaction system in which an F

在这种方法中,RH2ORH1SO2F被添加到氢氟酸中,形成一种浓稠溶液(氢键络合物),并且该溶液直接供应到使用F2气体的液相反应系统中。或者,RH2ORH1SO2Cl被添加到氢氟酸中,通过排放HCl转化为RH1ORH2SO2F,然后RH1ORH2SO2F被直接供应到使用F2气体的液相反应系统中。因此,可以安全进行氟化反应,以低成本生产具有目标结构的化合物,而不会引起异构化等问题。
