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) .
