Participants

Reaction Conditions

Reaction Steps

30 ml (27 g) of decahydronaphthalene and 0.5 g (2.3×10-4 ml) of a catalyst of 5% palladium on a barium sulfate support were added to the flask containing the 2,4-difluorobenzoylchloride. The reaction was purged with H2 for 0.25 hour, then the temperature was raised to 130° C. Hydrogen was dispersed through the system for 6 hours. The product 2,4-difluorobenzaldehyde was isolated as a colorless liquid. Yield 9.8 g (82%).
