Reactions of alkenols with H2O2—LiBr—Ce(NO3)3·6H2O or H2O2—LiBr—Ce(NH4)2(NO3)6 system led to bromination of the double bond to yield vicinal dibromoalkanols. The reaction proceeded highly selectively, no oxidation of the hydroxyl group virtually occurred.

reported for the conversion of alkenes to 1,2-dibromo alkanes via oxidative bromination using HBr paired with dimethylsulfoxide, which serves as the oxidant as well as cosolvent. The substrate scope includes 21 olefins brominated in good to excellent yields. Three of six styrene derivatives yielded bromohydrins under the reaction conditions.
