The reaction of HOCl with more highly substituted olefins in methylene chloride affords allylic chlorides in 60–80% isolated yields. The utility of the reaction is illustrated with the synthesis of Rose oxide and α-monoterpenes.

Sulfuryl chloride is a convenient reagent for the allylic chlorination of olefins bearing an isopropenyl or isopropylidenyl moeity. The substitution occurs with good yields and with allylic rearrangement, giving in most cases a secondary chloride.

Five different halofunctionalizations of acyclic monoterpenoids were performed using a combination of a hypervalent iodine(III) reagent and a halide salt. In this manner, the dibromination, the bromo(trifluoro)acetoxylation, the bromohydroxylation, the iodo(trifluoro)acetoxylation or the ene-type chlorination of the distal trisubstituted double bond occurred with excellent selectivity and moderate
The reaction of isopulegol with sulfuryl chloride leads in certain conditions to a mixture of 8-chloro citronellal and 6-chloro isocitronellal. The radical character of this fragmentation is supported by the result of two reactions known to proceed via an alkoxy radical.
