摘要：
Cycloalkylidene derivatives of the general formulae Ia to Ic ##STR1## where the dashed line is a possible additional chemical bond, the radicals R.sup.1 are identical or different C.sub.1 -C.sub.4 -alkenyl groups, R.sup.2 and R.sup.3 are each methyl or ethyl, R.sup.4 is hydrogen or one of the radicals R.sup.1, X is oxygen, methylene or a chemical bond, m is from 0 to 3 or, when X is methylene, is from 1 to 3, or, when X is methylene and R.sup.1 is methyl, is from 2 to 3 and n is from 0 to 3, are used as fragrance materials.
