    摘要: Process for the preparation of the compounds of the formulae Ia and Ib ##STR1## wherein A. 2,4,4-trimethylcyclohex-2-en-1-one oxime of the formula IIb ##STR2## is treated with a strong aqueous acid at from 30.degree. to 80.degree. C., preferably 40.degree. to 70.degree. C.,B. the resulting ketone of the formula IIIb ##STR3## is oxidized in a conventional manner, and C. if desired, the resulting compound Ib is isomerized in a conventional manner.Compounds of the formula A ##STR4## where R is one of the following radicals: --CH(OH)--CH.sub.2 --CH.dbd.CH.sub.2 (IIIb), --CH(OH)--CH.sub.3 (IIIc), --CH.sub.2 OH (IIId), --CH(OH)--CH.dbd.CH.sub.2 (IIIe), --CH(OCOCH.sub.3)--CH.sub.3 (IIIf), --CH.sub.2 --OCOCH.sub.3 (IIIg), --CO--CH.sub.2 --CH.dbd.CH.sub.2 (Ib), --CO--CH.sub.3 (Ic) and --CO--CH.dbd.CH.sub.2 (Ie).The compounds IIIb to IIIg, Ib, Ic and Ie are useful scents and aromas, and furthermore may become important intermediates for novel carotenoids. They can be prepared in a relatively simple manner from compounds which are very readily available.

    摘要: A process for the preparation of a-phenoxy-benzaldehyde which comprises contacting the 3-phenoxy-benzyl alcohol of the formula ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and represent hydrogen or halogen with an aqueous solution of a dichromate in the presence of aqueous sulphuric acid at a temperature in the range of 50.degree. to 125.degree. C. The 3-phenoxy-benzaldehyde can be in a mixture of other organic compounds such as obtained by hydrolyzing a 3-phenoxy toluene chlorinated in the side chain at a temperature of 140.degree.-210.degree.
