Reaktionsschritte

DCPD (dicyclopentadiene, Aldrich, 180 mL, 1.34 mol), butylacrylate (Junsei, 500 mL, 3.49 mol) and hydroquinone (2.7 g, 0.025 mol) were charged into a 2 L high-pressure autoclave, and the temperature was raised to 190° C. The resulting mixture was reacted for 5 hours with stirring at 300 rpm. After the reaction was completed, the reaction mixture was cooled and transferred to a distilling apparatus. The reaction mixture was distilled under a reduced pressure (1 torr) using a vacuum pump to yield the title compound at 80° C. (yield: 78%, exo/endo=55/45).
