Abstract
New odoriferous compounds, particularly the compounds having the following formula: ##STR1## wherein R is an aliphatic residue having the formula ##STR2## wherein R.sup.1 is a C.sub.1-4 alkyl, C.sub.1-4 alkylidene or C.sub.2-4 alkenyl, the sum of the carbon atoms being in those residues from 2 to 5, m and n being equal to zero or 1, p being 1, 2 or 3 and the dotted lines representing one or two optional double bonds. The invention also relates to a method for the preparation of new di-ketones I: as well as the use of I as odoriferous compounds in odoriferous compositions, which are characterized by a certain proportion of compounds having the formula I.

A compound of the formula ##STR8## wherein R signifies an aliphatic group of the formula ##STR9## in which R.sup.1 is C.sub.1-4 alkyl, C.sub.1-4 -alkylidene or C.sub.2-4 -alkenyl and the sum of the carbon atoms in these groups is 2-5, m and n are 0 or 1, p is 1, 2 or 3 and the dotted lines represent one or two optional double bonds, with the exception of 2-[3,3,5-trimethylcyclohexylacetyl]-cyclopentanone.
Odorant compositions containing an olfactorily effective amount of a compound of the formula ##STR16## wherein R signifies an aliphatic group of the formula ##STR17## in which R.sup.1 is C.sub.1-4 -alkyl, C.sub.1-4 -alkylidene or C.sub.2-4 -alkenyl and the sum of the carbon atoms in these groups is 2-5, m and n are 0 or 1, p is 1, 2 or 3 and the dotted lines represent one or two optional double bonds and at least one other odorant.
