Bis(acetylacetonato)dioxomolybdenum(VI)
Bis(acetylacetonato)dioxomolybdenum(VI) (CAS 17524-05-9), also written MoO2(acac)2, is an organomolybdenum coordination compound with the linear formula [CH3COCH=C(O-)CH3]2MoO2 and a molecular weight of 326.15 g/mol. It features a cis-dioxomolybdenum(VI) centre chelated by two acetylacetonate ligands. Used chiefly as a soluble molybdenum source and catalyst precursor in oxidation and epoxidation chemistry, and as a functional model compound for studying oxotransferase molybdenum enzymes.

Model compound for molybdenum oxotransferase enzymes
Serves as a functional model compound for the study of oxotransferase molybdenum enzymes, where the cis-dioxomolybdenum(VI) core helps probe oxygen-atom-transfer chemistry. It supports bioinorganic and mechanistic research.
Catalyst precursor for oxidation and epoxidation
As a soluble dioxomolybdenum(VI) complex, it is widely used as a precursor and catalyst in oxygen-atom-transfer reactions, including the epoxidation of olefins and related oxidations. It provides a well-defined, hydrocarbon-soluble molybdenum source.
Molecular precursor for molybdenum-based materials
The complex is employed as a molecular precursor for molybdenum oxide and related molybdenum-containing materials and thin films, decomposing cleanly on heating. It is convenient for solution and vapour-based deposition routes.
Coordination and organometallic research reagent
It is used as a starting material and reference compound in coordination and organometallic chemistry, for ligand-exchange studies and the preparation of further molybdenum complexes. Its defined structure makes it a useful synthetic building block.
