Abstract

Abstract : Immobilizedl -aspartic andl -glutamic acid were employed in the oxidation of sulfides, and 99% conversion and 97% selectivity were achieved. Abstract : l -Aspartic acid andl -glutamic acid were immobilized on hybrid silica and characterized by FT-IR, XPS, contact angle measurements, TGA, SEM and XRD. Employed as heterogeneous catalysts in the selective oxidation of sulfides with 30% H2 O2 at room temperature, 99% conversion and 97% selectivity were achieved with excellent substrate tolerance and recyclability.
