The chlorination of 3-methyl-2-butenyl phenyl sulfone with either hexachloroethane or 1, 1- dichloro-3-methyl-2-butenyl phenyl sulfone in basic medium gives rise to 1-chloro-3-methyl- 2-butenyl phenyl sulfone which in turn reacts in situ with electrophilic compounds to give a variety of products in good yields.
