Abstract
The use of monocyclic aldehydes as odorous materials, which can be produced through partial or total hydroformylation of (di)methyl-substituted cyclooct(adi)enes, is described. The fragrance enhancing capacity of the compounds is described in methods for their use both as perfumes and perfume enhancers or boosters.
