Both polonium derivatives are chemically very stable, requiring hot fuming nitric acid for their decomposition. However, they char rapidly under the intense alpha bombardment and attempted analyses with acetyl-acetone labeled with carbon-14 in the 1 and 3 positions were unsuccessful. It is interesting that the corresponding yellow oxide, prepared by treating (VI) with aqueous hydrogen peroxide, reverts to (VI) on treatment with aqueous alkali (12).

ALTERNATE PROTOCOL 2 ENZYMATIC MEASUREMENT OF CHOLESTEROL Test combination kits for enzymatic determination of cholesterol in food are now commercially available. For the determination of total cholesterol, esterified cholesterol is hydrolyzed to free cholesterol and fatty acid under mild alkaline conditions. Cholesterol oxidase oxidizes free cholesterol to cholest-4-en-3-one to generate hydrogen peroxide, which further oxidizes methanol to formaldehyde. Formaldehyde then reacts with acetyl acetone in the presence of NH4+ ions to form yellow lutidine dye, which is subsequently determined spectrophotometric al 1 y.

Cyclic peroxides are obtained from diketones when a five- or six-membered peroxide ring can be formed, as is the case with acetyl-acetone, acetonylacetone, triacetylmethane, and benzalacetylace-tone. In the reaction of 1,2-diketones with hydrogen peroxide, the C—C bond is broken to give carboxylic acids, without intermediate formation of a four-membered peroxide ring.37... 

Cyclic peroxides with six-membered rings are obtained from acetyl-acetone and hydrogen peroxide.41,42 Rieche et al. 1 obtained the 1,2-dioxolan derivative (36) (85%), and replacement of the hydroxyl groups in 36 with —OOH leads to 37.

ACETYL ACETONE (123-54-6) Forms explosive mixture with air (flash point 93°F/34°C). May form unstable peroxides on prolonged storage in air may undergo explosive polymerization. Reacts violently with strong oxidizers. Incompatible with aliphatic amines, alkanolamines, organic acids, isocyanates. 

In an efficient new one-pot phosphorylation method, O-diethylboiyl derivatives of carbohydrates were treated sequentially with phosphine enolate (41), prepared in situ from acetyl acetone and diphenylchlorophosphine (40), and hydrogen peroxide, to give sugar diphenylphosphinates (42), as illustrated in Scheme 8. Use of diethylchlorophosphite in place of chlorophosphine (40) furnished sugar diethylphosphates. ...
