Reaction Conditions

Reaction Steps

1-Acetoxy-1,3-butadiene (30.1 g, 0.268 mol) was dissolved in toluene (20 ml). To this was added butyl acrylate (37.9 ml, 0.265 mol) and hydroquinone (0.14 g). The colourless solution was heated at 120° C. for 26 hours under argon. More 1-acetoxy-1,3-butadiene (10.6 g, 0.095 mol) in toluene (2 ml) was then added, and heating continued for a further 68 hours. The solution was cooled then evaporated in vacuo to give a viscous yellow oil (69 g), which was used without further purification.
