Abstract
3-Acetyl-6,6-dimethyl-bicyclo [3.1.0]-2-hexene (Compound I) is prepared by contacting 2-(2-acetyl-3 -oxobutyl)-3,3-dimethyl- cyclopropanecarbaldehyde (Compound II) with a base in the presence of a solvent. Compound I is an intermediate in the manufacture of an insecticide, for example alpha-cyano-3-phenoxybenzyl 2-(2,2-dichlorovinyl)-3,3- dimethylcyclopropane-carboxylate. Compound II is preferably obtained from (+)-3-carene, a naturally occurring terpene.
