Allyl Alcohol → Allyl acetoacetate

Participants

Reaction Steps

A one liter reaction vessel equipped with a thermometer, a condenser and a dropping funnel was charged with 58 g (1 mol) of allyl alcohol, 100 g of dioxane and 0.41 g of sodium acetate (catalyst) under nitrogen blanket and heated to 60° C., to which 84 g (1 mol) of diketene was added dropwise for one hour. After completion of the addition, it was allowed to react for 2 hours with heating and dioxane was removed at a reduced pressure. The reaction product was further distilled to obtain 2-propenyl acetoacetate. It was identified by absorption at 1,742, 1,721 and 1,684 cm-1 in IR spectrum.
