Abstract
A process for producing sulfones in which sulfur dioxide is electrolytically transformed into SO.sub.2.sup.- ions and caused to react with organic compounds having functional groups replaceable by SO.sub.2.sup.-, in an aprotic organic solvent, to produce the corresponding organosulfone. According to the present improvement a phosphoric acid triester such as phosphoric acid tribenzyl ester, is added to the solvent as an organic compound capable of reacting with halogen ions of a salt, such as tetraalkylammoniumhalogenide or tetraalkylphosphoniumhalogenide, introduced into the solvent as a conductivity-promoting agent.
