Abstract :
Bismuth(III) salophen as a new catalyst has been synthesized. Structural properties of this complex have been studied by FTIR, XRD, DSC and TG analyses. The average of crystalline size of Bi-salophen particles was 86 nm. Thermal analyses show that the complex is stable over 300 °C. Catalytic activity of this catalyst has been investigated in oxidation of sulfides. Different kinds of sulfides have been oxidized to the corresponding sufoxides efficiently in the presence of sodium periodate as oxidant in glacial acetic acid as solvent at room temperature. These sulfides were selectively and completely converted into their corresponding sulfoxides in very short reaction times. Selectivity of this method was excellent which is another advantage of this method.
