Abstract
Alkynes and Cumulenes, XVIII. On the Nieuwland Acetylene Oligomerization: Structure of the TetramersThe tetramers formed during the Nieuwland acetylene oligomerization are shown to be (E)‐ and (Z)‐1,3,7‐octatrien‐5‐yne [(E)‐ and (Z)‐5] by their 1H and 13C NMR spectra as well as by chemical structure proof.
