Procedure
2.9 mmol of parabromo-anisole and 15 cm3 of 1.7 M HF--SbF5 superacid are contacted for 55 hours at ambient temperature in a poly(tetrafluoroethylene) container. Chromatographic analysis of the reaction products shows that a mixture of meta-bromo-phenol (25%) and meta-bromoanisole (40%) is formed, in a 65% yield.
