Methane → 2-Methyl-3-(2-methyl-5-isopropyl-cyclopent-1-en-1-yl)-propanal

Participants

Reaction Steps

19.2 g (0.1 Mole) of 2-methyl-3-(2-methyl-5-isopropenyl-cyclopent-1-en-1-yl)-propanal in 100 ml of dioxan were reduced by catalytic hydrogenation in the presence of traces of palladium over charcoal. After absorption of 2300 ml of hydrogen (10 hours) the reaction mixture was filtered and the clear filtrate evaporated under reduced pressure. The obtained residue was then distilled to give 18.3 g of the desired aldehyde;
