Transition-metal-free synthesis of (E)-vinyl sulfones from vinyl halides in water

A practical transition-metal-free procedure for the synthesis of (E)-vinyl sulfones through the coupling of vinyl halides with sodium sulfinates in water is reported. The reaction is strongly influenced by the presence of acids, and the use of nBu4NBr promotes its efficiency.

Polystyrene-supported selenosulfonates: Efficient reagents for regio- and stereocontrolled synthesis of vinyl sulfones

Two novel polystyrene-supported selenosulfonates reagents have been developed. As reagents for boron trifluoride catalyzed or AIBN catalyzed addition to olefins were successfully demonstrated and have been used for regioselective synthesis of vinyl sulfon

Selenosulfonation: Boron Trifluoride Catalyzed or Thermal Addition of Selenosulfonates to Olefins. A Novel Regio- and Stereocontrolled Synthesis of Vinyl Sulfones.

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.
