Abstract: Carbonyl compounds R1-CHR2-CHR3-CR4O (I, R1=H or an organic radical; R2-R4=H or C1-C4-alkyl) are prepared by selective hydrogenation of the alpha , beta -unsaturated carbonyl compounds R1-CR2=CR3-CR4O (II) in the liquid phase by means of hydrogen in the presence of a palladium catalyst and of from 15 to 50% by weight, based on (II), of a tertiary amine.
