Enantioselectivities up to 75 % have been found in the catalytic mono-oxidation of di-tert-butyl disulfide and related compounds as well as of ketene-S,S-acetals with an in situ generated chiral dioxirane. The effect of solvents on the enantiomeric excess has also been examined. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
