BOURGEONAL is a colorless to pale
yellow liquid with a powerful green, aquatic, aldehydic, lily of the valley odor.
It is recommended for use in toiletries and alcoholic fragrances, but also for
use in soaps and detergents. 3-[4-(1,1-Dimethylethyl)phenyl]propanal can be
prepared from 4-tert-butylbenzaldehyde by aldol reaction with acetaldehyde
and subsequent selective hydrogenation of the double bond of the resulting
4-tert-butylcinnamaldehyde or by reaction of tert-butylbenzene with
acrolein diacetate in the presence of a Lewis catalyst and saponification of the
resulting 3-[4-(1,1-dimethylethyl)phenyl]-1 (cipher)-propen-1-yl acetate.
