4,4'-Bis(dichloroiodo)biphenyl and 3-(dichloroiodo)benzoic acid are convenient recyclable hypervalent iodine reagents for vicinal chloromethoxylation or iodomethoxylation of unsaturated compounds. The reactivity of these reagents in the reaction of vicinal halomethoxylation is generally similar to dichloroiodobenzene and the advantage of their use is that the reduced forms of these reagents can be easily separated from the reaction mixture and reused for the regeneration of the reagents.
