Claims
- 1. A mixture of polyhydroindan carboxaldehydes defined according to the structure: ##STR141## wherein R.sub.7 represents a moiety selected from the group consisting of methyl and isopropyl prepared according to the process of reacting bicyclopentadiene having the structure: ##STR142## with an anhydrous alkanol having the structure:
- R.sub.7 --OH
- in the presence of a Lewis acid catalyst at reflux conditions for a period of time in order to effect substantially complete conversion to a mixture of compounds defined according to the structure: ##STR143## wherein the mixture in each of the compounds one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; then fractionally distilling the resulting reaction product in order to recover the said mixture of compounds defined according to the structure: ##STR144## and then reacting the resulting mixture having the structure: ##STR145## with carbon monoxide and hydrogen in the presence of an "oxo" reaction catalyst according to the reaction: ##STR146## at a temperature of between 150.degree. C. and 300.degree. C.; at a pressure of between 20 and 250 atmospheres; with a ratio of partial pressure of carbon monoxide:partial pressure of hydrogen being from 0.1:1 up to 1:0.1.
- 2. A process for augmenting or enhancing the aroma of a perfume composition, cologne or perfumed article comprising the step of intimately admixing with a perfume composition base, a cologne base or a perfumed article base, an aroma augmenting or enanching quantity of the composition of matter defined according to claim 1.
- 3. The composition of matter of claim 1 wherein R.sub.7 is methyl; wherein the mixture of compounds defined according to the structure: ##STR147## is fractionally distilled at a vapor temperature of from 58.degree. up to 97.degree. C. and a vacuum of from 1.3 up to 1.5 mm/Hg.; and wherein the mixture of compounds defined according to the structure: ##STR148## is fractionally distilled at a vapor temperature of from 124.degree.-140.degree. C. and a vacuum of 2.6-3.6 mm/Hg.
- 4. The composition of matter of claim 1 wherein R.sub.7 is isopropyl; wherein the mixture of compounds defined according to the structure: ##STR149## is fractionally distilled at a vapor temperature of from 42.degree. up to 59.degree. C. and a vacuum of from 0.8 up to 10.0 mm/Hg. pressure; and wherein the mixture of compounds defined according to the structure: ##STR150## is fractionally distilled at a vapor temperature of from 119.degree. up to 144.degree. C. and a vacuum of from 2.4 up to 3.0 mm/Hg.
- 5. The composition of matter defined according to claim 1 wherein in the reaction between the bicyclopentadiene and the alkanol, the Lewis acid catalyst is boron trifluoride etherate.
- 6. The composition of matter of claim 1 wherein in the "oxo" reaction the "oxo" reaction catalyst is a mixture of rhodium (III) trichloride hydrate and triphenyl phosphine or the "oxo" reaction catalyst is rhodium aceto acetate.
