Carbanions of dithiane monosulfone and dithiane monosulfonium salt react with nitroarenes in different ways: oxidative and vicariousnucleophilicsubstitution of hydrogen correspondingly.
Cyclohexanone monooxygenase catalysed oxidation of dithioacetals in combination with kinetic resolution gives enantiomerically pure (R)-monosulfoxides.
This work describes the preparative scale enantioselective oxidation of 1,3-dithiane to the corresponding monosulfoxide using whole-cell cultures of two bacteria, i.e. Acinetobacter calcoaceticus NCIMB 9871 and Pseudomonas sp. NCIMB 9872.

The selective oxidation of aromatic and aliphatic organosulfides with H2O2/H2O catalyzed by metal free ammonium salts has been explored. Reactions were performed using 2.5-5 mol % of catalyst loadings, isolating the corresponding sulfoxides in good to excellent yields (75-93%) and high selectivity. (C) 2013 Elsevier Ltd.
