Sulfones hydrobromination

Commercial Olefin Reactions. Some of the more common transformations involving a-olefins ia iadustrial processes iaclude the oxo reaction (hydroformylation), oligomerization and polymerization, alkylation reactions, hydrobromination, sulfation and sulfonation, and oxidation. 

A number of functional groups including sulfones, ethers and even alcohols (occasionally) can be accommodated during hydrobromination. Functional groups in close proximity to the C—C double bond can have an important directing effect (equations 88 and 89).133,134... 

Xfi-Dienes. The reagent undergoes a light-catalyzed regioselective addition to al-kenes, particularly mono-, 1,1-di-, and trisubstituted alkenes. The adducts undergo de-hydrobromination to a,p-unsaturated bromomethyl sulfones. On treatment with potassium...
