PROCESS FOR THE PREPARATION OF PENTAFLUOROETHOXY- AND PENTAFLUOROETHYL THIOBENZENE DERIVATIVES |
摘要 |
A process for the preparation of (pentafluoroethoxy)- and (pentafluoroethylthio)benzene derivatives either from phenol, thiophenol or from halobenzene. A halobenzene is reacted with trifluoroethanol or a phenol or a thiophenol is reacted with a compound of the formula CF3-CH2-O-R'. The product is chlorinated and the chlorinated product is fluorinated in liquid hydrofluoric acid in the presence of a Lewis acid. The compounds obtained by the process of the present invention are used as synthesis intermediates in the phytosanitary, pharmaceutical and veterinary industries, and are used in lubricants. |
