Abstract
4,4'-Dichloro-2,2'-bis(trifluoromethyl)diphenyl sulphoxide can be prepared from 2-bromo-4-chlorobenzotrifluoride and converted to the 2,2'-bis(trifluoromethyl)diphenyl sulphone, although the oxidation is remarkably difficult owing to the steric protection of the lone pair on sulphur by the two CF3 groups. Both the sulphoxide and the sulphone can be converted into the 4-chloro-4'-hydroxy single monomers.
