Synthesis of new sulfonyl chlorides on the basis of substituted diphenyl sulfones
-Sulfonation of substituted diphenyl sulfones with excess chlorosulfonic acid at 100°C yields as a rule the corresponding bis-sulfonyl chlorides. The reaction with an equimolar amount of 20% oleum yields products of sulfonation of only one benzene ring.
