ABSTRACT:
Processes and compositions are described for the use in tobacco flavor and aroma and perfume aroma augmenting, modifying, enhancing and imparting compositions and as tobacco, perfume and perfumed article aroma imparting and augmenting materials of one or more substituted dimethyl dihydroxy benzene and/or cyclohexadiene compounds, represented either by the equilibrium mixture: ##STR1## (and other tautomers) or by one of the compounds which is a constituent of said equilibrium mixture, wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond and R.sub.1 is either acetyl having the structure: ##STR2## or nitrile having the structure: ##STR3## with the proviso that when the dashed line is a carbon-carbon single bond, R.sub.1 is only nitrile and when the dashed line is a carbon-carbon double bond, R.sub.1 is either nitrile or acetyl.
Also described is the class of novel compounds represented either by the equilibrium mixture: ##STR4## (and other tautomers) or by one of the components of the equilibrium mixture wherein the dashed line is a carbon-carbon single bond or a carbon-carbon double bond.
The above-mentioned compounds, taken alone or in combination, provide and/or enhance and/or enrich "Oak Moss" notes in perfumes such as "Mousse de Chene". These compounds also provide sweet, slightly woody, "Oak Moss"-like aromas in the mainstream and sidestream on smoking and prior to smoking in tobacco articles such as cigarettes and cigars.
