Sulfonate properties

The most troublesome consequence of using concentrated sulfuric acid is in its sulfonating property. An aromatic molecule is likely to be more easily oxidized to a cation radical if it contains electron-donor substituents. But these substituents also make the molecule more susceptible to electrophilic attack, i.e. to sulfonation. This is the case, for example, with aromatic ethers and diarylsulfides. For example, 1,4-dimethoxybenzene undergoes 70-90% sulfonation within a few minutes in concentrated sulfuric acid, and only a low concentration of the cation radical can be obtained (Nishinaga et al.,...
