Zusammenfassung:1. Process for the preparation of sulphones and sulphoxides of the formula see diagramm : EP0137417,P5,F3 wherein R = H or optionally substituted C1 -C4 -alkyl, optionally substituted phenyl, nitro, sulpho, CN, halogen, OH, SH, NH2 , optionally substituted C1 -C4 -alkoxy, optionally substituted phenylazo, optionally further substituted benzotriazol-2-yl or naphthotriazol-2-yl, R1 = C1 -C4 -alkyl which is optionally substituted by chlorine, optionally substituted phenyl, nitro, sulpho, CN, OH, SH, NH2 , aminocarbonyl, optionally substituted C1 -C4 -alkoxy or the radical see diagramm : EP0137417,P5,F4 n = 1 to 4, x = 1 or 2, by the oxidation of sulphides of the formula see diagramm : EP0137417,P6,F1 characterised in that the oxidation is carried out in an aqueous medium at pH values of 3 to 14.
