4-Bromo-3,5-dichloroiodobenzene (4BDIB) is a halogenated anion that can be synthesized by the reaction of bromine and iodine with magnesium. It is used as a reagent in the synthesis of organic compounds. 4BDIB has been shown to react with dibromodifluoromethane to form 1,2-diiodobenzene and bromodifluoromethane. The electron-withdrawing group on the bromine atom in 4BDIB increases its reactivity with electrophiles such as Grignard reagents.
