Participants

Reaction Steps

38.8 g (269 mmol) of crude 5-norbornene-2-carboxylic acid was dissolved in 740 ml of solmix, 1.92 g of 5% palladium-carbon powder was added and the mixture was stirred for 17.5 hours under an atmosphere of hydrogen. The catalyst was filtered off, the solvent was distilled away, and 38.0 g of crude 2-norbornanecarboxylic acid was obtained. Crude yield: 100%.
