1,4-Pentadien-3-one

1,4-Pentadien-3-one is highly reactive, easily polymerized, used as polyfunctional annulation reagent; generally reacts by adding nucleophiles, dienes or radicals.

1,4-Pentadien-3-one is brieily storaged in solution (ether or hydrocarbon) at low temperature due to ease of polymerization. A toxic, flammable, lachrymatory liquid which must be used with care. As a dialkylating agent, it may be mutagenic. Wastes may be disposed of by treatment with ammonium hydroxide. Use in a fume hood.
