A new dioxo-molybdenum(VI) complex [MoO2(L)(CH3OH)] has been synthesized, using 2-[(2-hydroxypropylimino)methyl]phenol as tridentate ONO donor Schiff base ligand (H2L) and MoO2(acac)2. A monoclinic space group P21/c was determined by X-ray crystallography from single-crystal data of this complex. The high catalytic activity of this new Schiff base complex has been observed in the oxidation of various sulfides by urea hydrogen peroxide in ethanol affording sulfoxides and sulfones using different molar ratio of oxidant/sulfide in high/excellent yields and selectivity under mild and eco-friendly conditions. The relative high stability and desired turnover numbers have been observed for this Mo-catalyst in the oxidation reactions.
