Alkyl-4-cyclooctenyl carbonates and uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles

Abstract

Described are the 4-cyclooctenyl lower alkyl carbonates reaction products including a major proportion of said 4-cyclooctenyl alkyl carbonates and a minor proportion of bicyclooctanyl carbonates having the structure: ##STR1## wherein R.sub.5 is methyl or ethyl, said mixture being produced by: first reacting 1,5-cyclooctadiene with formic acid to form a mixture of 4-cyclooctenyl formate in a major proportion and bicyclooctanyl formate in a minor proportion and then reacting the resulting mixture with an alkyl carbonate in the presence of an alkali metal alkoxide to form a mixture of compounds defined above and uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles such as solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softeners, fabric softener articles, hair sprays, shampoos, bath oils and perfumed polymers.
