Abstract
Norbornane derivatives having hydrocarbon side chains, the processes for preparing the same and perfume compositions containing the same. The norbornane derivatives are represented by the following general formula (I) ##STR1## wherein C.sub.2 is an ethyl group, an ethylidene group or a vinyl group each connected to 5 or 6 position of the norbornane ring, each of R.sub.1 and R.sub.2 is a hydrogen atom or a methyl group, and R.sub.3 is a formyl group or a group represented by the following general formula (II) ##STR2## wherein R.sub.4 is a methyl group, an ethyl group, a n-propyl group or an isopropyl group, and X is a carbon atom of the norbornane ring. The above norbornane derivatives give a wide variety of woody fragrances and are useful as components for various perfume products.
