F. Bellesia et al., THE REACTION OF ALKYL PHENYL SULFIDES WITH MANGANESE-DIOXIDE AND ACETYL-CHLORIDE, Gazzetta chimica italiana, 123(5), 1993, pp. 289-291
In a one-pot reaction, manganese dioxide in stoicheiometric amounts an
d acetyl chloride transform alkyl phenyl sulphides into the correspond
ing 1-alkenyl phenyl sulphides; these latter products can undergo chlo
rination of the double bond promoted by the excess manganese dioxide.
