Ethylene is not only a substrate, but also a solvent : Catalytic intermolecular Pauson – Khand reactions of terminal alkynes were carried out in supercritical ethylene to provide 2‐substituted cyclopentenones in moderate to high yields [Eq. (1)]. Under these conditions, even a low pressure of CO (5 atm) is sufficient for the reaction to take place.
