Versuchsvorschrift

To a stirring mixture of 1-(3-furyl)-1-propanone (6.75 g, 0.0612 mol) in 150 mL of methylene chloride was added TEOF (13.2 mL, 0.079 mol) with stirring followed by 100 mg of p-toluenesulfonic acid monohydrate and the resulting mixture was stirred for 126 h. Potassium carbonate (2 g) was added to the above reaction mixture, stirred for 10 min, filtered, and concentrated in vacuo. The residue was distilled (35 mm, 82°-85° C.) to afford 2.5 g (29%) of 1-(3-furyl)-1-ethoxy-ethylene (Formula III: R3 =R4 =H; R5 =CH3CH2O;R6 =3-furanyl), as a clear oil.
