Abstract

a. Procédé pour la préparation de sulfones. b. On électrolyse de l'anhydride sulfureux dissous dans un solvant aprotique avant ou après addition d'un composé halogéné. On ajoute à la solution un sel formant des ions halogènes et un triester d'acide phosphorique. c. Préparation de dibenzylsufone.at. Process for the preparation of sulfones. b. Sulfur dioxide dissolved in an aprotic solvent is electrolyzed before or after addition of a halogen compound. A halogen ion forming salt and a phosphoric acid triester are added to the solution. vs. Preparation of dibenzylsufone.
