Alcoholate Clusters (“Aggregates”) and Their Role in Alkyne‐Forming Elimination Reactions

Abstract

The decisive step in the elimination of HCl from the (Z)- or (E)-chlorohept-enyne (1) with potassium tert-butyl alcoholate involves participation of dimeric, trimeric or—more rarely—tetrameric alcoholate aggregates; the dehydro-chlorination could proceed according to a “conveyor mechanism”, as indicated for the (Z)-compound in anti-(3).
