Abstract
In this study, a new catalyst including polymeric imidazolium ionic liquid functionalized Cobalt (II) Schiff base complex [PIL-SB-Co (II)] was prepared and characterized using various analyses like FT-IR, H-NMR, FE-SEM, Energy-dispersive X-ray, thermogravimetric analysis, and ICP-OES. Then, its catalytic activity was studied in oxidation reaction of sulfides and alcohols. This polymeric heterogeneous catalyst can catalyze the oxidation reactions in water as a green solvent, and mild conditions (room temperature) with good to excellent yields of sulfoxides, aldehydes, and ketones as worthwhile and critical products. Highlights First preparation and characterization of poly ionic liquid functionalized Co (II) Schiff base catalyst. First oxidation reaction of sulfides and alcohols catalyzed by polymeric ionic liquid Schiff base complex. Oxidation reaction of sulfides and alcohols to sulfoxides and aldehydes and ketones in water as a green solvent and room temperature. Reusable catalyst at least for five runs.
