Abstract
We have synthesized Schiff’s base of Fe

@chitosan with 4,4'-diselenobisbenzaldehyde
(Fe

@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

) to oxidize sulfides to corresponding sulfoxides at room temperature. It has been found
that yield of sulfoxides depend on the amount of H

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

.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.
