Pauson-Khand reactions between alkynehexacarbonyldicobalt complexes and ethylene are promoted by trimethylamine N-oxide. The carefully optimised mild reaction conditions at either moderate or atmospheric pressures of ethylene provide convenient and effective methods for the synthesis of cyclopentenones by this organometallic technique.
