Synthesis, characterization, and X-ray structure of n'-(2-hydroxy-5-methylbenzylidene)-4-trifluoromethylbenzohydrazide and its dioxidomolybdenum(vi) complex with catalytic property

ABSTRACT

A new hydrazone compound N’-(2-hydroxy-5-methylbenzylidene)-4-trifluoromethylbenzohydrazide (H₂L) was prepared. Based on H₂L, a new dioxidomolybdenum(VI) complex [cis-MoO₂L(MeOH)], was obtained. Single crystals of H₂L and the complex were obtained by slow evaporation of methanolic solution containing the compounds, and were characterized by elemental analysis, infrared spectroscopy, and single-crystal X-ray diffraction techniques. The geometry around the molybdenum center is distorted octahedral in which the tridentate benzohydrazone ligand with two anionic oxygens and one neutral imine nitrogen occupies meridional position. The octahedral geometry of the cis-dioxomolybdenum center is additionally completed by a coordinated methanol solvent molecule. The complex was tested for the homogeneous oxidation of various olefins.
