4-Hydroxybenzoic Acid → Ethenyl 4-hydroxybenzoate

Participants

Reaction Steps

2000 g of dichloromethane, 24.9 g of vinyl acetate, 40.0 g of 4-hydroxybenzoic acid, 0.79 g of palladium acetate and 3.5 g of potassium acetate were charged into a separable flask of the same type as used in Reference Example 3 and subjected to reaction at 50° C. for 6 hours, while replacing the flask inside atomosphere with a nitrogen gas. After completion of the reaction, the reaction mixture was washed successively with an aqueous 0.5N sodium carbonate solution and water, and then treated in th same manner as in Reference Example 3, whereby 4.8 g of vinyl 4-hydroxybenzoate having the following chemical formula was obtained (yield: 10%): ##STR5##
