Synthesis, Crystal Structure, and Catalytic Property of Dioxomolybdenum(VI) Complex Derived from 4-Bromo-N’-(4-diethylamino-2-hydroxybenzylidene)benzohydrazide

Li Wang, Yong-Jun Han, Qing-Bin Li, Ling-Wei Xue


A novel dioxomolybdenum(VI) complex, [MoO2L(MeOH)], where L is the anion of 4-bromo-N’-(4-diethylamino-2-hydroxybenzylidene)benzohydrazide, has been synthesized and characterized by physico-chemical methods and single crystal X-ray determination. In the complex the Mo atom is in octahedral coordination, with three donor atoms of the hydrazone ligand, two oxo groups, and one methanol O atom. The complex exhibits catalytic property for the sulfoxidation reactions. In the presence of the complex a 93% conversion of the sulfide to the corresponding sulfoxide was observed within 60 min and the 100% conversion was achieved after 2 h.
