| Popis: | A dioxomolybdenum(VI) complex [MoO2L(EtOH)] (I), derived from the hydrazone ligand 2‑bromo-N'-(3,5-dichloro-2-hydroxybenzylidene)benzohydrazide has been prepared and characterized by physico-chemical and spectroscopic methods, as well as single crystal X-ray diffraction (CIF file CCDC no. 1840671). The hydrazone ligand coordinates to the Mo atom through the phenolate oxygen, imino nitrogen, and enolic oxygen. The Mo atom is six-coordinate in an octahedral geometry. Complex I shows high catalytic activity and selectivity in the epoxidation of cyclohexene with tert-butylhydroperoxide as primary oxidant. |
