An unprecedented double C-S bond formation method has been developed to prepare both symmetric and unsymmetric diarylsulfones with simple arenes in a single step. This represents the first example that K2S2O8 can be employed as a highly effective sulfonating agent to synthesize diarylsulfones. The reaction demonstrates excellent reactivity, good functional group tolerance and high yields.

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.

In dichloromethane at 0 deg C, the acyl fluorides 3 insert sulfur trioxide to form the thermolabile acylcarbonic fluorosulfonic anhydrides 4 in good yield.Acylation of non-activated arenes with the anhydrides 4 is impossible since they decompose upon warming into constituent compounds; with the SO3 thus liberated, diarylsulfones 6 are formed.
