Abstract
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.
Highlights
Molybdenum complexes with multi-dentate ligands have received remarkable attention in recent years for their catalytic properties[1] and molecular structures.[2]
As a continuation of such work, we report in this paper the synthesis, structure, and catalytic property of a new dioxomolybdenum(VI) complex, [MoO2L(MeOH)], where L is the anion of 4-bromo-N’-(4-dimethylamino-2-hydroxybenzylidene)benzohydrazide (Scheme 1)
The complex was prepared by the reaction of the hydrazone ligand with MoO2(acac)[2] in a 1:1 molar ratio (Scheme 2)
Summary
Molybdenum complexes with multi-dentate ligands have received remarkable attention in recent years for their catalytic properties[1] and molecular structures.[2]. Crystal data of the complex were collected with a Bruker Apex II diffractometer using Mo Kα radiation (0.71073 Å). The data were processed with SAINT9 and corrected for absorption using SADABS.[10] Multi-scan absorption corrections were applied with ψ scans.[11] Structure of the complex was solved by direct method using SHELXS-97 and refined by full-matrix least-squares
