Open publisher page 56 citations

Abstract

The direct C–H methylsulfonylation of alkenes using inorganic sodium metabisulfite as the sulfur dioxide surrogate is described. This method provides convenient access to ( E )-2-methyl styrenyl sulfones in good yields. In general, the in situ generated methyl radical from di- tert -butyl peroxide undergoes a methylsulfonylation process with the combination of sulfur dioxide.
