Amphiphilic perfluoroalkylated sulfones and sulfonate betaines

Journal of Fluorine Chemistry, 2007
Abstract Two types of perfluoro alkyl-containing amphiphilic sulfones 7 – 9 and 13 – 15 , respectively, and sulfonate betaines 23 – 32 were prepared using 2-[(perfluoroalkyl)methyl]oxiranes ( 1–3 , R F  = C 4 F 9 , C 6 F 13 , C 8 F 17 ) or 3-(perfluoroalkyl)propyl iodides ( 16 and 17 , R F  = C 6 F 13 , C 8 F 17 ) as the starting compounds ...

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.
