Abstract

The present invention relates to processes for the preparation of compounds of the formula (Ia)

by reacting styrene with a secondary alkanol and the hydrogenation of the resulting phenyl-substituted tertiary alkanol. In addition, the invention relates to compounds of the formula (Ia) and to the use of such compounds as fragrances, and also to compositions which comprise compounds of the formulae (Ia) and (Ib).

First claim

The invention claimed is:

1. A method for improving the olfactory properties and/or concealing undesired intrinsic odors of a cosmetic composition, textile detergent or cleaner for hard surfaces, the method comprising adding a compound of formula (Ia) to the cosmetic composition, the textile detergent or the cleaner for hard surfaces,

wherein R 1 and R 2 , independently of one another, are selected from C 4-7 -cycloalkylalkyl- with a total of 4 to 7 carbon atoms, C 3-7 -cycloalkyl-, which is optionally substituted with 1, 2, or 3 C 1-7 -alkyl, and C 1-7 -alkyl-, and R 1 and R 2 together comprise in total 3 to 11 carbon atoms.

2. The method according to claim 1 , wherein R 1 and R 2 , independently of one another, are selected from C 1-7 -alkyl-.

3. The method according to claim 1 , wherein R 1 is methyl and R 2 is ethyl.

4. The method according to claim 1 , wherein R 1 and R 2 together comprise in total 3 to 5 carbon atoms.

5. The method according to claim 1 , wherein the adding of the compound of formula (Ia) includes adding a compound of formula (Ib)

6. The method according to claim 1 , wherein R 1 and R 2 , independently of one another, are selected from C 1-7 -alkyl, and C 4-7 -cycloalkylalkyl- with a total of 4 to 7 carbon atoms.

7. The method according to claim 1 , wherein R 1 and R 2 , independently of one another, are selected from C 1-7 -alkyl, and C 3-7 -cycloalkyl-, which is optionally substituted with 1, 2, or 3 C 1-7 -alkyl.

8. The method according to claim 2 , wherein the compound of formula (1a) is selected from the from consisting of 1-cyclohexyl-3-methyl-3-hexanol, 1-cyclohexyl-3-methyl-3-heptanol, 1-cyclohexyl-3-methyl-3-octanol, 1-cyclohexyl-3-methyl-3-nonanol, 1-cyclohexyl-3,4-dimethyl-3-octanol, 1-cyclohexyl-3,5-dimethyl-3-octanol, 1-cyclohexyl-3,6-dimethyl-3-octanol, 1-cyclohexyl-3,7-dimethyl-3-octanol, 1-cyclohexyl-3,4,4-trimethyl-3-heptanol, 1-cyclohexyl-3,5,5-trimethyl-3-heptanol, 1-cyclohexyl-3,6,6-trimethyl-3-heptanol, 1-cyclohexyl-5-ethyl-3-methyl-3-heptanol, 1-cyclohexyl-3,5-dimethyl-3-heptanol, 2,4-dicyclohexyl-2-methyl-2-butanol, 1-cyclohexyl-4-cyclopentyl-3-methyl-3-pentanol, 1-cyclohexyl-3-ethyl-3-hexanol, 1-cyclohexyl-3-ethyl-3-heptanol, 1-cyclohexyl-3-ethyl-3-octanol, and 1-cyclohexyl-3-ethyl-3-nonanol.
