Synthesis, Characterization, and X-Ray Structure of [cis-MoO₂L(MeOH)] (L = N′-(5-Chloro-2-Hydroxybenzylidene)-3-Chlorobenzohydrazide) and Its Catalytic Property

Abstract

The synthesis and characterization of [cis-MoO₂L(MeOH)] (L = N′-(5-chloro-2-hydroxybenzylidene)-3-chlorobenzohydrazide) are described. The dioxomolybdenum complex was prepared from 1:1 reaction mixture containing the benzohydrazone ligand and MoO₂(acac)₂. Orange single crystals were obtained by slow evaporation of methanolic solution containing the complex, 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 a 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.
