Hydrazone-based dioxidomolybdenum(<scp>vi</scp>) complexes: catalytic oxidation of omeprazole sulfide
Four hydrazone-based molybdenum(VI) complexes, namely [MoO<sub>2</sub>(L<sub>1</sub>)·H<sub>2</sub>O] 1, [MoO<sub>2</sub>(L<sub>2</sub>)·H<sub>2</sub>O] 2, [MoO<sub>2</sub>(L<sub>3</sub>)·H<sub>2</sub>O] 3, [MoO<sub>2</sub>(L<sub>4</sub>)·H<sub>2</sub>O] 4, were successfully synthesized utilizing hydrazone ligands H2L1-H2L4. The structural and physicochemical properties of these ligands and their corresponding molybdenum complexes were elucidated through a comprehensive array of spectroscopic and analytical techniques. Single-crystal X-ray diffraction analysis (SC-XRD) unambiguously confirmed that all four complexes adopt a distorted octahedral arrangement around the metal center. Additionally, powder X-ray diffraction (P-XRD) studies verified the bulk purity of the synthesized complexes. The catalytic potential of all complexes was evaluated in the oxidation of omeprazole sulfide using green oxidant <i>i.e.</i> hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) as an oxidant under both dark and illuminated conditions. Remarkably, all complexes exhibited excellent catalytic efficiency, achieving complete conversion of the omeprazole sulfide substrate with 100% product selectivity.
