Abstract
Described is a process for preparing a mixture of t-mercapto terpenes defined according to the structure: ##STR1## and .alpha.-terpineol defined according to the structure: ##STR2## including the step of reacting the compound defined according to the structure: ##STR3## with an alkali metal thiocyanate defined according to the structure: ##STR4## wherein M represents alkali metal such as sodium, potassium or lithium in the presence of a phase transfer catalyst. The resulting product is then treated with lithium aluminum hydride followed by aqueous mineral acid to form a mixture of .alpha.-terpineol and the compound defined according to the structure: ##STR5## which mixture is useful for its organoleptic properties.
