A fast and efficient protocol is proposed for the synthesis of diaryl sulfoxides in the ionic liquid 1-butyl-3-methylimidazolium chloroaluminate, [bmim]Cl·AlCl3, N=0.67, by employing arenes and thionyl chloride. The ionic liquid plays a dual role of Lewis acid catalyst and solvent, under ambient conditions, offering good yields of the product. The influence of the Lewis acidity of the ionic liquid on the extent of conversion is studied.

We determined molar Kerr constants and dipole moments in dioxane solutions for a number of diaryl sulfones with various substituents in the aromatic nuclei.The data obtained were analyzed to establish the preferential molecular conformations.It was shown that diaryl sulfones occur in solution mainly in the form of orthogonal or planar-orthogonal conformers, or as an equilibrium between these two.In the orthogonal conformer both aromatic rings are perpendicular to the plane of the CArSCAr bonds, whereas in the planar-orthogonal conformer one ring is coplanar and the other orthogonal to this plane.The orthogonal orientation of aromatic rings relative to the CArSCAr plane originates from the ?-conjugation of the nuclei and the sulfonyl gruop of the sulfone molecules.
