Abstract
Disubstituted cycloalkanones are prepared from one of 2-cyclopentylidenecyclopentan-1-one, 2-cyclohexylidenecyclohexan-1-one, 2-cyclopentylidenecyclohexan-1-one, or 2-cyclohexylidenecyclopentan-1-one. The resulting compounds were analyzed for their odor characteristics. The different compounds exhibited varied odor characteristics, which were not predictable from the structures of the compounds. The compounds are useful in the preparation of fragrance compositions and products formed from same.
