Abstract
Described are isopropyl tetramethylindan musks defined according to the generic structure: ##STR1## wherein R.sub.3 and R.sub.4 are each acetyl or methyl with the provisos: PA2 (a) one of R.sub.3 or R.sub.4 is methyl; PA2 (b) when R.sub.4 is methyl, then R.sub.3 is acetyl and PA2 (c) when R.sub.4 is acetyl, R.sub.3 is methyl and organoleptic uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles. Also described is a process for preparing same by means of first rearranging a tetralin derivative defined according to the structure: ##STR2## to form at least one compound defined according to the structure: ##STR3## and then reacting the compound having the structure: ##STR4## with a compound of the genus: ##STR5## wherein Z represents acetoxy, chloro or bromo in order to form at least one compound defined according to the structure: ##STR6## wherein one of R.sub.1 or R.sub.2 is methyl and the other of R.sub.1 or R.sub.2 is hydrogen.
