Reactions of potassium dihaloiodates with arylcyclopropanes and polycyclic compounds containing a cyclopropane fragment characterized by different degrees of strain lead to formation of mixed 1,3-halogenation products. If iodohalogenation should give rise to products having a iodine atom in the benzylic position, 1,3-dichloro or 1,3-dibromo derivatives are formed. Iodohalogenation of exo-tricyclo[3.2.1.0(2,4)]octane is stereoselective and is accompanied by Wagner-Meerwein rearrangement.

The reaction of phenylcyclopropane with iodine and various mercury(II) salts affords regiospecifically 1,3-bifunctionalized phenylpropanes following the Markownikoff rule; in the case of cyclopropyl phenyl ketone, the reaction with mercury(II) chloride-iodine leads to (3-chloro-1-iodopropyl) phenyl ketone.
