Procedure

An isomeric mixture of diethyl benzene (268.44 g, 2.0 moles), anhydrous methane sulfonic acid (96.1 g, 1.0 mole) and phosphorus oxychloride (25.6 g, 2.17 moles) were heated at 90° C. with stirring for 8 hours. Treatment of the reaction mixture after cooling was the same as in Example 1 and 25 g (12% yield) of methyl diethylphenyl sulfone was obtained.
