(57) [Abstract] [Purpose] Norbornadiene, dicyclopentadiene or bicyclo [2.2.1] hept-5-ene-2,3 -A carbon-carbon double bond contained in its bicyclo [2.2.1] ring from a norbornene which is a dicarboxylic acid anhydride 1 Norbornanes having two carboxylic acid ester groups introduced therein are produced with high catalytic activity. Composition: norbornadiene, dicyclopentadiene or bicyclo [2.2.1] hept-5-ene-2,3 -The norbornenes, which are dicarboxylic acid anhydrides, and alcohols, carbon monoxide and oxygen, are (1) palladium metal or a compound thereof, (2) a copper compound, (3) a chlorine compound and (4) a manganese or zinc compound. By reacting in the presence of a catalyst containing the norbornene bicyclo [2. 2.1] A norbornane in which two carboxylic acid ester groups are introduced for each carbon-carbon double bond contained in the ring is produced. |
