A new protocol has been developed for the formation of C?Se and C?S bonds by the direct selenosulfonylation of alkenes. This protocol is operationally simplistic, has a wide substrate scope, uses readily available seleno and sulfonyl sources, and is amenable to gram-scale synthesis. This reaction represents a significant addition to the limited number of reactions available for the intermolecular selenide difunctionalization of alkenes and would be useful for the synthesis of sulfur- and selenium-containing molecules.

Se-Phenyl areneselenosulfonates 1 add to a variety of olefins to produce β-phenylseleno sulfones 2.The reaction may be performed in the presence of boron trifluoride etherate to produce chiefly or exclusively Markovnikov products arising from a stereospecific anti addition.Alternatively, the addition may be thermally induced to afford anti-Markovnikov products generated by a nonstereospecific free-radical process.The two modes of addition achieve complementary regiospecificity.The β-phenylseleno sulfones are converted in high yield to vinyl sulfones by stereospecific oxidation-elimination with m-chloroperbenzoic acid.

The reaction of phenyl areneselenolsulfonates with unhindered olefins affords β-phenylselenosulfone adducts, usually with high regio- and stereoselectivity.
