Vanadyl Acetylacetonate

Vanadyl acetylacetonate is a chemical compound. It is used in organic chemistry as a reagent in the epoxidation of allylic alcohols in combination with tert-butyl hydroperoxide (TBHP). The VO(acac)2-TBHP system exclusively epoxidizes geraniol at the allylic alcohol position. For comparison, another epoxidizing agent m-CPBA, reacts with both groups, creating the products in a two to one ratio, favoring the allylic position away from the alcohol. TBHP oxidizes VO(acac)2 to a vanadium(V) species which coordinates the alcohol of the substrate and the hydroperoxide.

Vanadyl Sulfate

Vanadyl sulfate is a well known inorganic compound of vanadium. This very hygroscopic blue solid is one of the most common sources of vanadium in the laboratory, reflecting its high stability. It features the vanadyl ion,VO2+, which has been called the "most stable diatomic ion." Vanadyl sulfate is an intermediate in the extraction of vanadium from petroleum residues, a major commercial source of vanadium. It is a component of some food supplements and drugs. Vanadyl compounds mimic the effects of insulin, although humans seem to have no dietary requirement for vanadium.It is used as a dihydrate in dyeing and printing textiles, to make glass, and to add blue and green glazes to pottery.
