Abstract

Described are carbon-containing functional groups substituted 4,5,6,7-tetrahydro-polyalkylated-4-indanes, isomers thereof, process for processes for preparing same, and uses thereof. The 4,5,6,7-tetrahydro-polyalkylated-4-indanes have the generic structure: ##STR1## Wherein G and R.sub.1-5 are as defined in the specification. The aforementioned materials have fragrance properties or are intermediates for materials which have fragrance properties. Also described are processes for producing the aforementioned substances.
