Abstract: Aliphatic aldehydes of the general formula I (I) where R1 is hydrogen or methyl, R2 is a straight-chain or branched alkyl radical of 1 to 4 carbon atoms and the two radicals X are each hydrogen or together form a further C-C bond, in particular 2,5,7,7-tetramethyloctanal, 2,4,5,7,7-pentamethyloctanal, 2-ethyl-5,7,7-trimethyloctanal and 2,5,7,7-tetramethyl-2-octen-1-al, are used in scent compositions and are prepared by a process in which an aldehyde of the general formula II (II) is condensed with an aldehyde of the general formula III (III) in the presence of an aldol condensation catalyst to give the substituted octenal of the general formula I, and, if required, the latter is partially hydrogenated or reduced to give the ocorresponding octanal of the formula I.
