The use of substituted 5-phenylpentan-1-ols, 5-phenylpentanals, 5-phenylpentanitriles, 5-phenylpentanoic acid and lower alkyl esters thereof and 5-phenylpentanyl esters of C,-C,aliphatic acids as fragrance materials is disclosed. The subject fragrance materials are, in large measure, novel compounds. The subject materials possess unique fragrance notes and are cost-effective materials.

Fragrance materials

The use of 2-methyl-3-cyclohexylpropanol, esters thereof or mixtures thereof as fragrance materials is disclosed. The subject materials possess unique fragrance notes and are cost-effective materials. The esters are novel compounds.

The use of 3-methyl-5-cyclohexylpentanol, 3-methyl-5-cyclohexylpentanal or mixtures thereof as fragrance materials is disclosed. The subject materials possess unique fragrance notes and are advantageous in that they are cost-effective.

The present invention relates to a perfumery material composed of a mixture of 3-methyl-5-phenyl-pentanenitrile and 3-methyl-5-cyclohexyl-pentanenitrile, which can be combined with other perfumery materials.

Nitrile perfumery material

A process for the preparation of a formylated aromatic compound comprising contacting an aromatic compound with (i) a halogenated compound in the presence of a Lewis acid, and (ii) a base, is described. The subject process provides an efficient and effective means of preparing formylated compounds which may be useful in a wide variety of applications.

Process for formylation of aromatic compounds

The present invention relates, inter alia, to novel alkyl indane aldehyde compounds having fragrant musk-like aroma.

Alkyl indane aldehyde compounds

The present invention relates, inter alia, to novel alkyl tetralin aldehyde compounds having fragrant musk-like aroma.

Alkyl tetralin aldehyde compounds

The present invention relates to novel indane compounds, such as, for example, 5-formyl-1,1,2,3,3,4,6-heptamethylindane, a compound of the formula ##STR1## and to compositions including the same, as well as to methods for their preparation. Compounds and compositions of the invention possess a fragrant musk-like aroma and have utility in the perfumery and/or other industries.

Indane compounds and compositions

The present invention relates to novel formate ester indane compounds having fragrant musk-like aroma.

Formate ester indane compounds

The present invention relates to novel formate ester tetralin compounds having fragrant musk-like aroma.

Tetralin formate ester aroma chemicals

The present invention relates to novel nitrile and aldoxime indane compounds, such as 1,1,2,3,3,4,6-heptamethylindane-5-nitrile and 1,1,2,3,3,4,6-heptamethylindane-5-aldoxime, and to compositions containing the same. Compounds and compositions of the invention possess a fragrant musk-like aroma, and thus are useful in the perfumery and/or other industries.

Nitrile and aldoxime indane compounds and compositions

A process for the preparation of a carene-dienophile diadduct in high yield is provided. Delta-3-carene is reacted with a Diels-Adler dienophile, preferably maleic anhydride, at a dienophile:carene molar ratio of at least 1.5:1 and a temperature of at least 150.degree. C. The diadduct produced by the reaction of delta-3-carene and a Diels Alder dienophile, preferably maleic anhydride, is useful as a curing agent in epoxy resin systems.

Process for the preparation of delta-3-carene diadducts

The present invention relates to a novel indane compound which is 5-formyl-1,1,2,3,3,4,6-heptamethylindane, a compound of the formula ##STR1##

Novel heptamethyl indane compound

Novel acylated tetramethyl and pentamethyl isopropyl indane compounds having a fragrant musk-like aroma are disclosed.
