Isopropenyl acetate is an organic compound, which is the acetate ester of the enol tautomer of acetone. This a colorless liquid is significant as the principal precursor to acetylacetone.
Preparation and reactions
Isopropenyl acetate is prepared by treating acetone with ketene.[1] Upon heating over a metal surface, isopropenyl acetate rearranges to acetylacetone.
