New aminotetrazole derivatives as hydrogen bonding catalysts. A green and selective oxidation of organosulphides with H2O2 in H2O

Abstract

The oxidation of organosulphides catalysed by hydrogen bonding donors derived from aminotetrazole has been studied. The oxidation reaction was performed in a H₂O solution using H₂O₂ as a versatile, green and chemoselective new approach to sulphoxides. Sulphoxide compounds are obtained in high yields and excellent selectivity through a new and easy to perform oxidation protocol. Aminotetrazole derivatives can be recycled by filtration and reused several times without expensive purification procedures.
