Metallbindungsphänomene: Alkoholat‐Aggregate als unmittelbare Teilnehmer an Eliminierungsreaktionen

Abstract

Abstract In solvents of low polarity it is neither a monomolecular nor a dissociated alcoholal species which effects dehydrohalogenation of vic ‐dihaloalkanes and vic ‐dihalocycloalkanes but rather a dimeric, trimeric or tetrameric alcoholate aggregate. This behavior has important implications for the stereochemical outcome of such elimination reactions.
