Procedure

DCPD (Aldrich, 248 mL, 1.852 mol), allylacetate (Aldrich, 500 mL, 4.63 mol), and hydroquinone (0.7 g, 0.006 mol) were put in a 2 L autoclave. After heating to 190° C., reaction was carried out for 5 hours while stirring the autoclave at 300 rpm. After the reaction was completed, the reaction mixture was cooled down and transferred to a distillation unit. The reaction mixture was distilled at 1 torr twice using a vacuum pump at 56° C. to obtain the product (yield: 30%). The molar ratio (mol %) of exo/endo isomers of the product was 57:43.
