Procedure

One gram of 5% palladium-on-carbon and 8 g. of 2,5-dimethylhex-4-en-1-al is stirred in 50 ml. of ethanol under excess hydrogen at one atomsphere pressure and at room temperature until the theoretical amount of hydrogen is absorbed (about 24 hours). Then, 2 ml. of dichloromethane is added and the mixture filtered. The filtrate is concentrated under reduced pressure to yield 2,5-dimethylhexan-1-al.
