Fluorinated ethers ArOCF2CFHO& are obtained in good yield by base-catalyzed addition of phenols to perfluoroallryl vinyl ethers, CF&FO& (&= C3F7, C3F70CF (CF3) CF2, CH302CCF2CF20CF (CF3) CF2). Reaction of sodium phenoxides with fluorinated vinyl ethers and hexachloroethane affords chlorinated ethers ArOCF&FClO&. Treatment of BrCF2CFBrOC3F7 with sodium phenoxide in the presence of CF2= CFOC3F7 gives ...
