摘要：

Only 0.0022 mole equivalents of the catalyst [Co2(CO)8] are necessary for the preparation of the cyclopentenone 1 from 1-heptyne. ethylene, and CO with an exchange number of about 220. This first catalytic Pauson-Khand reaction (PKR) with an unstrained alkene affords 1, a precursor of methyl-transdihydrojasmonate that is important for the perfumery industry, in about 50% yield. The main byproducts of this PKR were also identified and possible routes for their formation proposed.
