METHOD OF PREPARING 4,4'-DICHLORODIPHENYL SULFOXIDE Russian patent published in 2000 - IPC

Abstract RU 2159764 C1

FIELD: fine organic synthesis, more particularly preparation of chlorinated aromatic sulfoxides. SUBSTANCE: 4,4'-dichlorodiphenyl sulfoxide is prepared by reacting sulfide with sulfuryl chloride. Diphenyl sulfide is first dissolved in carbon tetrachloride, and reaction is carried out in the presence of aluminium chloride at 0-5 C. Invention makes it possible to prepare 4,4'-dichlorodiphynyl sulfoxide by technologically simple method using available compounds with high yield (94%). Method uses simple equipment and has industrial application. EFFECT: more efficient preparation method.
