FREMGANGSMADE TIL FREMSTILLING AF ORGANISKE FORBINDELSER, DER INDEHOLDER CYCLOPROPANRINGSYSTEMET |
摘要 |
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. |
