Dj. Procter et al., SELENOXIDE - SULFONIC-ACID ADDUCTS - A NEW SYSTEM FOR THE MILD, SELECTIVE OXIDATION OF SULFIDES TO SULFOXIDES, Synlett, (3), 1994, pp. 204-206
The development of a selenoxide - sulfonic acid system for the mild an
d selective oxidation of sulfides to sulfoxides is reported. Various s
elenoxide and sulfonic acid combinations were studied in the search fo
r an effective system. A mechanism for the oxidation is proposed and t
he potential for the development of an asymmetric oxidation system is
assessed.
