Template effects of a clay–chelate adduct on the asymmetric oxidation of alkyl phenyl sulphide by sodium metaperiodate
Abstract
Cyclohexyl phenyl sulphide adsorbed by Δ-tris(1,10-phenanthroline)nickel(II)–montmorillonite was oxidized by sodium metaperiodate at 25°C in water to give (S)-cyclohexyl phenyl sulphoxide with an optical purity of 78%.
