What is Vo ACAC 2 used for?
VO(acac)21 is one the best and most extensively used catalysts for epoxidation of unsaturated alcohols. Mainly studied by Sharpless et al., 1/tert-butyl hydroperoxide (TBHP) was shown to be a highly regio- and stereoselective system for the epoxidation of allylic 10-12 and homoallylic alcohols.

|Molar mass||197.94 (dihydrate)|
|Appearance||yellow solid (dihydrate)|
|Solubility in water||insoluble|
What is the charge of vanadium ion?
The charge of the vanadium ion +5. The oxidation state of O is -2 for most compounds except peroxides. A charge-neutral ionic compound is present when 2 vanadium(V) ions and 5 oxide ions are present. The sum of the positive and negative charges becomes 0.
Why is acetylacetonate a stronger ligand than vanadium?
However, acetylacetonate is a stronger ligand that displaces the water molecules. Since Vanadium is bonded to oxygen with a V=O bond, only 2 acetylacetonate will only be able to form coordinate bond with the vanadium central metal ion to form the VO (acac)2 complex with a square pyramidal geometry as shown in Figure 3.
How do enolate anion and acetylacetonate ligand bind to oxovanadium?
The enolate anion is able to act as a bidentate ligand as it can chelate onto the oxovanadium metal ion with the two oxygen atoms as the binding sites to form the VO (acac)2 complexes. Two acetylacetonate ligands are able to bind to the oxovanadium metal and form a square pyramidal complex.
What is the oxidation number of vanadium in VO (acac) 2?
The complex of the VO (acac)2 has an oxidation complex of +4 which the vanadium (IV) ion exists as a d1.
What is the geometry of VO2+ and acetylacetonate?
Before the reaction of the VO2+ with the acetylacetonate, VO2+ is coordinated to five water molecules and existed as octahedral geometry. However, acetylacetonate is a stronger ligand that displaces the water molecules.
