Abstract
Novel syntheses of dihalovinylcyclopropanecarboxylates, including potent insecticides, are described. The processes begin with the reaction between an alkenol and an orthoester to produce a .gamma.-unsaturated carboxylate, followed by the catalyzed addition of a carbon tetrahalide to the double bond and dehydrohalogenation to produce a cyclopropane derivative.
