1-Acetoxy-1,3-butadiene

Abstract

AcO [1515-76-0] C 6 H 8 O 2 (MW 112.13) InChI = 1/C6H8O2/c1-3-4-5-8-6(2)7/h3-5H,1H2,2H3 InChIKey = NMQQBXHZBNUXGJ-UHFFFAOYAQ (2π or 4π partner in cycloaddition reactions; 1 mono-oxygenation allows high levels of regiocontrol 2 ) Alternate Name: 1,3-butadienyl acetate. Physical Data: bp 60-61 • C/40 mmHg; d 0.945 g cm −3 . Form Supplied in: colorless liquid, available as an unspecified mixture of (E) and (Z) isomers. 3 Handling, Storage, and Precautions: classified as a flammable liquid and is reputed to be toxic. Compound polymerizes upon extended storage and can be regenerated by distillation. Avoid polymerization initiators. Diene performs best when stored in the cold.
