Selectivity in the pentacarbonyliron-promoted cyclocarbonylation of enediynes

Article abstract of DOI:10.1021/om00011a040

Cyclocarbonylation reactions of a series of enediynes, promoted by pentacarbonyliron, proceed selectively on the diyne, resulting in the formation of cyclopentadienone-iron tricarbonyl complexes, without competing enyne cyclocarbonylation.
