ABSTRACT = {We have synthesized Schiff’s base of Fe<sub>3</sub>
O<sub>4</sub>
@chitosan with 4,4'-diselenobisbenzaldehyde
(Fe<sub>3</sub>O<sub>4</sub>
@CSSe) composite and used it as acatalyst for the oxidation of sulfides, having some
advantageous properties such as eco-friendly, cost-effective and highly efficient magnetic
biocatalyst of selenium. The synthesized schiff’s base was characterized by different physical
characterization techniques such as Fourier transform infrared spectroscopy (FT-IR), X-ray
diffraction (XRD), Vibrating sample magnetometer (VSM)and Dynamic light scattering (DLS).
Further, we used the resulting schiff’s base as a catalyst in the presence of a green oxidant
(H<sub>2</sub>
O<sub>2</sub>
) to oxidize sulfides to corresponding sulfoxides at room temperature. It has been found
that yield of sulfoxides depend on the amount of H<sub>2</sub>
O<sub>2</sub>
, loading catalyst and various solvents
condition. Besides, more efficiently oxidation of dibutyl sulfide observed in the solvent-free
condition with the yield of 94 per cent in the presence of 20mg Fe<sub>3</sub>
O<sub>4</sub>
@CSSe and 0.5 mL
H<sub>2</sub>
O<sub>2</sub>
.Thus, the magnetic schiff’s base catalyst applied to oxidation of a broad range of sulfides.
This may help enrich and develop future research on organic synthesis.},
