Abstract: This invention concerns processes for preparing compounds having the structure ##STR1## wherein each of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 is the same or different and represents hydrogen or a lower alkyl group and wherein each dashed line represents a carbon-carbon single bond or a carbon-carbon double bond. Those compounds in which all three dashed lines represent carbon-carbon double bonds are prepared by reacting phenols and 2-alkylidene-1,4-disubstituted butanes. Selective reduction of these compounds yields those in which at least one dashed line represents a carbon-carbon single bond. Most of the compounds so prepared are new compounds. All are useful as fragrance materials either directly and/or in compositions and/or have useful fixative properties in fragrance compositions.

Abstract: A process for introducing an allyl-positioned carbonyl group into a 2,6,6-trimethylcyclohexene ring which carries a polyenyl radical in the 1-position, by oxidizing the ring with a halogen(V)-oxyacid or a salt of such an acid, and the new oxo compounds obtainable by the said process, which may be used as dyes for foodstuffs or cosmetics. The oxidation is carried out in the presence of a catalyst and of an inert diluent or solvent, in an acid medium. Suitable catalysts are bromine and iodine and the oxides of elements of groups Va, VIa, VIIa and VIII of the periodic table.
