Uses and applications

What the substance is used for, by industry and function

Chemical intermediate for the perfume component, isobornyl acetate, misc specialty aromatics, and the insecticides isobornyl thiocyanoacetate and toxaphene.

Essential oils extracted from leaves and fruits of Schinus areira (Anacardiaceae) were tested for their repellent, toxic and feeding deterrent properties against Tribolium castaneum (Coleoptera: Tenebrionidae) larvae and adults. A topical application assay was employed for the contact toxicity study and filter paper impregnation for the fumigant assay. A treated diet was also used to evaluate the repellent activity and a flour disk bioassay for the feeding deterrent action and nutritional index alteration. The essential oil of the leaves contained mainly monoterpenoids, with alpha-phellandrene, 3-carene and camphene predominant, whereas that from the fruits contained mainly alpha-phellandrene, 3-carene and beta-myrcene.

The leaf essential oil showed repellent effects, whereas that from the fruit was an attractant. Both oils produced mortality against larvae in topical and fumigant bioassays, but fumigant toxicity was not found against adults. Moreover, both essential oils produced some alterations in nutritional index. These results show that the essential oils from S. areira could be applicable to the management of populations of Tribolium castaneum. (Schinus areira oil).

How it is made

(+)-alpha-Pinene is converted into (+)-bornyl chloride by the action of dry hydrogen chloride in a Wagner-Meerwein rearrangement. Base-catalyzed dehydrohalogenation of the (+)-bornyl chloride gives racemic camphene.

Isomerization of alpha-pinene in the presence of solid acidic mineral catalysts

From pinene by catalytic isomerization or from bornyl chloride by heating with alkali in the presence of abietenesulfonic acid.
