Aromatic sulfonation XI: Sulfonation of benzene and toluene with sulfur trioxide; sulfone formation and sulfonic acid isomer distribution. [PDF]
Recueil des Travaux Chimiques des Pays-Bas, 1964 AbstractThe sulfonation of benzene and toluene with sulfur trioxide without solvent has been studied extensively.With benzene at low conversion benzenesulfonic acid and diphenylsulfone are the only products. At 25° the sulfone: sulfonic acid ratio changes from 0.2 to 0.6 on varying the SO3 : C6H6 ratio from 0.13 to 1.3.

Drug Reactions to the Sulfones
Archives of Dermatology, 1970In a brief temporal span, two patients treated with diaminodiphenyl sulfone had significant reactions to the drug. These were severe hemolysis and the hitherto undescribed reaction of cholestatic jaundice. Review of the literature in regards to indications for sulfone therapy and the drug-associated reactions was accomplished.
