, p. 533 - 542 (1991)
Ferric porphyrins bearing chiral binaphthalene moieties on their both faces catalyze asymmetric oxidation of sulfides with iodobenzene as an oxidant in moderate to good optical and chemical yields.Enantiomeric excesses (e.e.) were markedly improved in 2-3 times by the addition of 1-methylimidazole.The mechanism of oxidation and chiral induction are discussed.
Catalytic and Asymmetric Oxidation of Sulphides with Iron Complexes of Chiral "Twin Coronet" Porphyrins
Naruta, Yoshinori,Tani, Fumito,Maruyama, Kazuhiro
, p. 1378 - 1380 (1990)
Iron porphyrins that are modified on both faces by chiral binaphthalenes catalysed asymmetric oxidation of sulphides in fair to good enantiomeric excesses and excellent turnover numbers of the catalysts in the presence of 1-methylimidazole.

Optically pure chiral sulfoxides can be formed in good to excellent yields by sequential displacement reactions of organometallic reagents on the 1,2,3-oxathiazolidine-S-oxide formed from ephedrine and thionyl chloride, a modification of the Wudl and Lee procedure.
