The ability of a rhodium catalyst derived from phosphine‐phosphite ligands to hydrogenatively resolve a set of structurally diverse α,β‐unsaturated vinyl sulfoxides is reported. The practicality of the methodology was applied to the preparation of precursors of biologically active compounds.
A selective and efficient method for the oxidation of sterically hindered sulfides to sulfoxides is described, which involves the use of hydrogen peroxide in methanol in the presence of catalytic amounts of a mixture of sulfuric acid and isoamyl, isopropyl or tert-butyl alcohol.
