Versuchsvorschrift

15.7 g (110 mmol) of crude 5-norbornene-2-carboxylic acid was dissolved in 300 ml of ethanol, 1.55 g of 5% palladium-carbon powder was added, and the mixture was stirred under an atmosphere of hydrogen for 24 hours. After the catalyst was filtered off, the solvent was distilled off, and 14.5 g of crude 2-norbornanecarboxylic acid was obtained. Crude yield: 94%.
