Reaction Conditions

Reaction Steps

After 10 ml of acrolein commercially available from Aldrich, Co. is dissolved in 50 ml of anhydroust ethanol, 19 ml of triethylorthoformate and p-toluene sulfonic acid are added to the solution, and the resulting mixture is allowed to reflux under a nitrogen atmosphere for 5 hours. After that, the resulting solution is cooled to a temperature of 5° C., extracted with diethyl ether, washed with 5% sodium bicarbonate (NaHCO3) aqueous solution, dried with anhydrous magnesium sulfate (MgSO4), and then evaporated under a reduced pressure to remove ethanol. Next, the material is fractionally distilled, thereby giving 8.4 g of 3,3-diethoxy-1-propene.
