Hexafluorobenzene reacts readily with a variety of trimethylsilyl ethers ROSiMe3 (R = CF3CH2, FCH2CH2, H(CF2)nCH2 (n = 2, 4), CF3(CF2)6CH2, CF3(CF2)5CH2CH2, Me3SiOCH2CH2, C6F5OCH2CH2, C6H5, 4-FC6H4) to give from mono- to hexapolyfluoroalkoxy- and polyfluoroaryloxy-benzenes.The structure of C6(OCH2CF3)6 has been confirmed by single-crystal X-ray analysis.The perfluorinated ether C6F5OCF2CF3 may be synthesized from C6F5OCH2CF3 by chlorination and subsequent fluorination with SbF3/SbCl5.The chlorination of 5,6,7,8-tetrafluoro-1,4-benzodioxane is also discussed.
