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.
