Zusammenfassung:The method of sulphones of penicillanic acids preparation during which crystal potassium permanganate is used in oxidation of penicillanic acids, their sulphoxides and their mutual compounds is described. Crystal potassium permanganate is added, gradually, into 0,8-3 mol of reaction mixture to 1 mol of water soluble salt of corresponding acid. The reaction is processed in the concentration of initial water-soluble salt of corresponding acid in water from 1 to 30 percent of mass quantity in temperature ranging from -5 to 30 degrees Celsius.
