Process for producing 1,1-dimethyl-3-indanones, products produced thereby and organoleptic uses thereof

BACKGROUND OF THE INVENTION
The instant invention relates to 1,1-dimethyl-3-indanones defined according to the structure: ##STR2## wherein R.sub.1 and R.sub.2 are the same or different and each represents hydrogen or methyl with the proviso that at least one of R.sub.1 and R.sub.2 is methyl, a process for preparing same and uses of same in augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes.
Inexpensive chemical compounds which can provide intense and long lasting leathery, amber, honey-like, orange flower, saffron-like, dried fruit-like, tobacco, woody, fruity and ozoney aromas with leathery, amber, orange flower absolute-like topnotes are highly desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfumery compositions are high in cost, unobtainable at times, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.
There is, accordingly, a continuing effort to find synthetic materials which will replace, enhance or augment the fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of the synthetic materials either have the desired nuances only to a relatively small degree or they contribute undesirable or unwanted odor to the compositions.
Bicyclic ketones are known for use in perfumery in the prior art. Thus, Arctander, "Perfume and Flavor Chemicals (Aroma Chemicals)" 1969, at monograph number 1791 and U.S. Pat. No. 2,912,462 issued on Nov. 10, 1959 discloses the compound having the structure: ##STR3## as having a dry, woody, amber-like and somewhat orris-like aroma. The compound having the structure: ##STR4## is commercially sold as "KETONE BD-9".
The compounds having the structure: ##STR5## wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond is disclosed as being useful in perfumery (having a wood or ambergris aroma) in Japanese Published Patent No. 57-53768 assigned to the Takasago Perfumery Company.
The compound having the structure: ##STR6## is disclosed as being useful in perfumery in U.S. Pat. No. 3,847,993 issued on Nov. 12, 1974. This compound is indicated to be produced using the compound having the structure: ##STR7## as a precursor according to the reaction: ##STR8##
The compound having the structure: ##STR9## is disclosed as being useful in perfumery by Ferrero and Heig, Helv. Chim. Act. Volume XVII, Fasc. VI (1959) Number 228 at page 2111. This compound having the structure: ##STR10## is produced from the compound having the structure: ##STR11## which is indicated to be an intermediate. Furthermore, in Ferrero and Heig, the compound having the structure: ##STR12## is indicated to be an intermediate for producing acylated indanes from the compound having the structure: ##STR13## The compound having the structure: ##STR14## is indicated as compound XXIX. The compound having the structure: ##STR15## is indicated as compound XXVIII in Example C-3 at page 2119 of Ferrero and Heig.
Furthermore, the reaction: ##STR16## wherein R is lower alkyl such as methyl is disclosed in U.S. Pat. No. 3,078,319 issued on Feb. 19, 1963 wherein it is indicated that the resulting indanes may be acylated.
In addition, the use of cobolt acetate bromide and oxygen for the production of ketones is shown by Hay, et al, in the Canadian Journal of Chemistry, 43,1306 (1965). In this process, tetralin is oxidized to the corresponding ketone, that is .alpha.-tetralone.
Nothing in the prior art, however, indicates the unexpected, unobvious and advantageous properties of the compound having the structure: ##STR17## Furthermore, nothing in the prior art indicates the perfumery uses of the compounds having the structures: ##STR18## as covered by the genus having the structure: ##STR19## wherein R.sub.1 and R.sub.2 are the same or different and each represents hydrogen or methyl with the proviso that at least one of R.sub.1 and R.sub.2 is methyl. The compounds having the structures: ##STR20## are novel compounds.

THE INVENTION
The present invention provides compounds defined according to the generic structure: ##STR37## wherein R.sub.1 and R.sub.2 are the same or different and each represents methyl or hydrogen with the proviso that at least one of R.sub.1 and R.sub.2 is methyl.
The composition of matter of our invention produced according to the process of our invention is capable of augmenting, enhancing or providing leathery, amber, honey-like, orange flower-like, saffron-like, dried fruit, tobacco, woody, fruity and ozoney aromas with leathery, amber or orange flower absolute-like topnotes to perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener articles, drier-added fabric softener articles, fabric softener compositions, cosmetic powders, hair preparations and perfumed polymers and the like).
The substances of our invention are first prepared by reacting toluene or meta-xylene with isoprene in the presence of an acidic catalyst, e.g., sulfuric acid, to form a tri or tetra methyl indane defined according to the generic structure: ##STR38## wherein R.sub.1 and R.sub.2 are the same or different and each represents hydrogen or methyl with the proviso that at least one of R.sub.1 and R.sub.2 is methyl, according to the reaction: ##STR39## The parameters for this reaction are set forth in U.S. Pat. No. 3,078,319 issued on Feb. 19, 1963, the specification for which is incorporated by reference herein.
The resulting indane derivative defined according to the structure: ##STR40## is then reacted with oxygen using an appropriate catalyst in order to form the 1,1-dimethyl-3-indanones of our invention defined according to the structure: ##STR41## wherein R.sub.1 and R.sub.2 are defined, supra, according to the reaction: ##STR42## In fact, the reaction can be carried out using oxygen or air.
The reaction temperature may be in the range of from about 25.degree. C. up to about 150.degree. C. at a pressure of from about 1 atmosphere up to about 10 atmospheres. The reaction takes place in the presence of a solvent such as acetic acid, or benzene or in the absence of a solvent. The reaction takes place using a catalyst, such as cobolt naphthenate, cobolt acetoacetate or cobolt diacetate. Other transition metal (e.g., chromium maganese and copper) catalysts may also be used and these transition metal catalysts are the standard oxidation catalysts.
The reaction may be also carried out using air rather than oxygen. When using air as a reactant, the indane derivative defined according to the structure: ##STR43## is charged into an autoclave with the appropriate catalyst, preferably a cobolt salt, such as cobolt aceto acetate.
The amount of catalyst used in the oxidation reaction may be from about 0.1% up to about 1% by weight of the reaction mass.
When using air, the air is introduced into the autoclave at a set velocity, preferably about 500 cc per minute. Preferably, when using air the reaction pressure may vary from about 50 up about 500 psig, more preferably between about 100 and 200 psig.
Examples of reaction products of our invention and their organoleptic properties are set forth in the following table:

One or more of the 1,1-dimethyl-3-indanones prepared in accordance with the process of our invention and one or more auxiliary perfume ingredients including, for example, alcohols, aldehydes, ketones other than the 1,1-dimethyl-3-indanones of our invention, turpenic hydrocarbons, nitriles, esters, lactones, natural essential oils and synthetic essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in leathery, amber, spicy, vetiver-like, "chypre" and patchouli fragrances. Such perfume compositions usually contain:
(a) the main note or the "bouquet" or foundation stone of the composition;
(b) modifiers which round-off and accompany the main note;
(c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and
(d) topnotes which are usually low boiling fresh smelling materials.
In perfume compositions, it is the individual components which contribute their particular olfactory characteristics, however, the overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, the 1,1-dimethyl-3-indanones prepared in accordance with the process of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of the 1,1-dimethyl-3-indanones prepared in accordance with the process of our invention which will be effective in perfume compositions as well as in perfumed articles (e.g., anionic, cationic, nonionic or zwitterionic detergents, soaps, fabric softener compositions, fabric softener articles and perfumed polymers) and colognes depends upon many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.01% of the 1,1-dimethyl-3-indanones prepared in accordance with the process of our invention or even less (e.g., 0.005%) can be used to impart, augment or enhance leathery, amber, honey, orange flower, saffron-like, dried fruit, tobacco, woody, fruity and ozoney aromas with leathery, amber, orange flower absolute-like topnotes to soaps, cosmetics, anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, microporous polymers, particularly acrylic resins, polyethylenes and other products. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.
The 1,1-dimethyl-3-indanones prepared in accordance with the process of our invention are useful (taken alone or together with other ingredients in perfume compositions) as (an) olfactory component(s) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations such as creams, deodorants, hand lotions and sun screens; powders, such as talcs, dusting powders, face powders, microporous "perfumed" slow reease polymers and the like.
When used as (an) olfactory component(s) in perfumed articles, as little as 0.005% of the 1,1-dimethyl-3-indanones prepared in accordance with the process of our invention will suffice to impart, augment or enhance leathery, amber, honey, orange flower, saffron-like, dried fruit, tobacco, woody, fruity and ozoney aromas with leathery, amber and orange flower absolute-like topnotes. Generally, no more than 6% of the 1,1-dimethyl-3-indanones of our invention based on the ultimate end product is required in the perfumed article. Accordingly, the range of use of the 1,1-dimethyl-3-indanones of our invention in perfumed articles, per se, is from about 0.005% up to about 6% by weight based on the perfumed article.
In addition, the perfume composition or fragrance composition of our invention can contain a vehicle or carrier for the 1,1-dimethyl-3-indanones prepared in accordance with the process of our invention. The vehicle can be a liquid such as a non-toxic alcohol, e.g., ethyl alcohol, a non-toxic glycol, e.g., propylene glycol or the like. The carrier can also be an absorbent solid such as a gum (e.g., gum arabic, guar gum or xanthan gum or combination thereof) or components for encapsulating the composition (such as gelatin as by coacervation) or polymers such as urea formaldehyde prepolymers which form a urea formaldehyde polymer capsule wall around a liquid perfume scentor.
It will thus be apparent that the 1,1-dimethyl-3-indanones prepared in accordance with the process of our invention can be utilized to alter, modify or enhance sensory properties particularly organoleptic properties such as fragrances of a wide variety of consumable materials.
The following Examples I-IV set forth means for preparing the 1,1-dimethyl-3-indanones of our invention. The Examples following Example IV, Example V et seq, set forth illustrations of organoleptic utilities of the 1,1-dimethyl-3-indanones of our invention.
All parts and percentages given herein are by weight unless otherwise specified.
