Isopropenyl acetate is an organic compound, which is the acetate ester of the enol tautomer of acetone. This colorless liquid is significant commercially as the principal precursor to acetylacetone .
In a novel kilogram-scale metal-free Meerwein arylation the diazonium salt is formed from 2-nitroaniline, the alkene isopropenyl acetate is an adduct of propyne and acetic acid and the reaction product 2-nitrophenylacetone: [7] Metal free meerwein arylation
Isopropyl acetate decomposes slowly on contact with steel in the presence of air, producing acetic acid and isopropanol. It reacts violently with oxidizing materials and it attacks many plastics. [5] Isopropyl acetate is quite flammable in both its liquid and vapor forms, and it may be harmful if swallowed or inhaled. [6]

The enzyme acetylacetone dioxygenase cleaves a central carbon-carbon bond of acetylacetone, producing acetate and 2-oxopropanal. The enzyme is iron(II)-dependent, but it has been proven to bind to zinc as well. Acetylacetone degradation has been characterized in the bacterium Acinetobacter johnsonii.

In organic chemistry, 1-propenyl (or simply propenyl) has the formula CH=CHCH 3 and 2-propenyl (isopropenyl) has the formula CH 2 =C-CH 3. These groups are found in many compounds. These groups are found in many compounds.
From left to right: the two isomeric groups propyl and 1-methylethyl (iPr or isopropyl), and the non-isomeric cyclopropyl group. In organic chemistry, a propyl group is a three-carbon alkyl substituent with chemical formula −CH 2 CH 2 CH 3 for the linear form.
