Vanadyl acetylacetonate Usage And Synthesis

Reaction

Catalyst for the hydroxyl-directed epoxidation of olefins.
Catalyst for the asymmetric oxidation of disulfides.
Catalyst for the Mannich reaction.
Catalyst for sulfoxidation of alkanes.

Chemical Properties

powder

Uses

Vanadium(IV) Oxide Acetylacetonate is used as a catalyst in organic chemistry and is also an intermediate in synthetic reactions, such as the synthesis of novel oxovanadium complexes that display antitumor activity.

Uses

Vanadyl acetylacetonate may be used as a precursor for the preparation of vanadium dioxide thin films for applications in “intelligent” window coating and data storage.

Flammability and Explosibility

Not classified

reaction suitability

reagent type: catalyst

Purification Methods

It crystallises from acetone. [cf Fernelius & Bryant Inorg Synth V 105 1957, Beilstein 1 IV 3672.]

Toxics Screening Level

The initial threshold screening level (ITSL) for vanadium oxide bis (2,4-pentanedionate) is 0.1 μg/m3 based on annual averaging time.
