Abstract

The use of (dichloroiodo)benzene enables a mild and rapid nucleophilic chlorination of readily available secondary and tertiary alkyl phenyl sulfides. Enantioenriched benzylic sulfides can be converted to their corresponding inverted chlorides with high stereospecificity. The chlorination of sulfa-Michael derived sulfides provides elimination-sensitive β-chloro carbonyl and nitro compounds in good yields.
