Abstract
The synthetic potential of the catalyst-free reaction of arylstannanes and sulfonyl
chlorides, for the generation of asymmetric diarylsulfones, is described. Moreover, the
efficiency of the reaction is improved using diarylstannanes as starting substrates. All
the reactions studied went, exclusively, through an ipso-substitution and give
acceptable yields of sulfones from aryl sulfonyl chlorides supporting either electronreleasing
or electron-attracting substituents. A special work up is carried out in order to
recover the di- and trialkyltin chlorides generated as subproducts
