Abstract

The use of aldehydes as odorous materials, which can be produced through partial or total hydroformylation of cyclooctadienes, except cyclooctane aldehydes, is described. The fragrance enhancing capacity of the compounds is described in methods for their use both as perfumes and perfume enhancers or boosters.
