Abstract

1335626 Sulphones; sulphoxides EASTMAN KODAK CO 27 May 1971 [1 June 1970] 17621/71 Heading C2C Sulphides are oxidized to sulphoxides or sulphones and sulphoxides to sulphones by means of H 2 O 2 in the presence of a water-soluble zirconium salt. A chelating agent may be present. Examples prepare bis(2-hydroxyethylsulphonylmethyl) ether, bis(2-hydroxyethylsulphonylethyl) ether, butyl sulphone, benzyl sulphone, methyl phenyl sulphone, phenyl sulphone and tetrahydrothiophene-1,1-dioxide in two stage reactions from the corresponding sulphides via the sulphoxides (not isolated).
