A triphasic phase-vanishing (PV) system comprised of an alkane, perfluorohexanes, and bromine was successfully combined by photoirradiation to efficiently generate hydrogen bromide, which underwent radical addition with 1-alkenes in the hydrocarbon layer to afford terminal bromides in high yields.

A solution of hydrogen bromide (HBr) in 1,4-dioxane was prepared and investigated for its ability to brominate alcohols, and hydrobrominate alkenes. This study revealed that the brominating ability of this HBr/1,4-dioxane solution is equal or superior to that of hydrobromic acid or HBr in acetic acid. The solution of HBr in 1,4-dioxane is robust, exhibiting no decomposition of the solvent, and retaining 97% of its original concentration, when kept at ?25 °C for 30 days. This solution is a liquid alternative to HBr gas without protic solvents.

A synthesis is described of alkyl chlorides by reaction of methoxy hydroperoxides, prepared from 1-alkenes by ozonisation in methanol, with ferric chloride: RCH=CH2 --> RCH(OOH)OCH3 --> R. --> RCl.Yields of 1-chlorotetradecane were about 60percent; those of other halides from 38 to 57percent.
