Disulfides are the key component of organic and bioorganic process such as disulfide bond formation on peptides, control cellular redox potential in biological systems and they are used as protecting agent of thiolsunder oxidative condition. The most important method of producing disulfids is the oxidation of thiols.a board range of reagent and catalysts are used for oxidation of thiols to disulfides like molecular oxygen, metal oxides, nitric oxides, halogens, sodium perborate and DMSO. Tin oxide is a metal oxide that is wildly used in different area like electrode material, a transparent electrode, glass sensing electrode and they are used as hydrogen,carbon monoxide, hydrocarbon and alcohol sensor.In this work SnO2 nanostructures were synthesized by simple precipitation method by adding ammonia directly to SnCl2 solution and it was used as catalyst foroxidation of thiols derivatives to disulfides. It was a selective and highly efficient catalyst. SnO2 nanostructures were characterized by XRD and SEM and products of thiol oxidation were identified by GC-mass spectroscopy.
