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 met
Catalytic and direct methyl sulfonylation of alkenes and alkynes using a methyl sulfonyl radical generated from a DMSO, dioxygen and copper system

This paper describes an efficient method to β-keto methyl sulfones and (E)-vinyl methyl sulfones using DMSO as the substrate. The methyl sulfonyl radical generated from DMSO in the presence of catalytic Cu(i) under O2 atmosphere is believed to be involved in this reaction. Isotopic labeling and 18O2 experiments were performed to investigate the reaction mechanism.
Heck vinylations using vinyl sulfide, vinyl sulfoxide, vinyl sulfone, or vinyl sulfonate derivatives and aryl bromides catalyzed by a palladium complex derived from a tetraphosphine

The adverse impact of sulfur compounds on catalytic performance is well known. The tetraphosphine cis,cis,cis-1,2,3,4-tetrakis[(diphenylphosphino) methyl]cyclopentane in combination with allylchloropalladium dimer affords an efficient catalyst for the Hec
