Aryltrimethylsilanes, ArSiMe3, react with sulphur trioxide in carbon tetrachloride to give the sulphonic esters, ArSO2OSiMe3, which undergo hydrolysis readily to the sulphonic acids ArSO3H. The reaction provides a means of introducing a sulpho group at a specific position of the aromatic ring; thus from m-tolyltrimethylsilane, m-toluenesulphonic acid is obtained in 80 % yield.
