Synthesis and characterization of a dioxo -molybdenum(VI) unsymmetrical salophen complex as an efficient nanocatalyst for oxidative desulfurization of liquid fuels

In the present work, unsymmetrical salophen ligand was synthesized in good yield and then metallated with MoO۲(acac)۲ to obtain MoO۲(salophen -OH) complex. The prepared MoO۲(salophen -OH) complex was characterized by FT-IR, UV-Vis, ۱HNMR, and elemental analysis. The synthesized MoO۲(salophen -OH) complex was successfully employed as a new and efficient homogeneous catalyst for the selective oxidation of thiophene (Th) and benzo thiophene (BT) as impurities in liquid fuels to the corresponding sulfones with ۳۰% H۲O۲ as oxidant under mild reaction conditions.
