An efficient and convenient method for the synthesis of aromatic sulfones catalysed by ZrO2/S2O82- solid superacid

A manipulatively simple and rapid procedure for the synthesis of diaryl sulfones from arylsulfonyl chlorides with aromatic compounds is described; the reaction is conducted under Friedel-Crafts conditions in the absence of solvent using ZrO2/S2O82- as catalyst in 78-93% yields.
