Thermolysis of adducts formed from tricarbonyl(vinylketene)iron(0) complexes and alkynes leads to either cyclopentenediones or phenols and its outcome is controlled by the electronic properties of the C-1 substituent of the adduct; the phenols may be synthesised directly and regioselectively from tricarbonyl(vinylketene)iron(0) complexes and electron-rich alkynes.

Alkynes add to tricarbonyl(vinylketene)iron(0) complexes to generate stable 1:1 adducts, the structures of which were determined by an X-ray crystal structure analysis of the adduct formed from tricarbonyl(5-phenyl-3-iso-propyl-1-oxapenta-1,2,4-triene)iron(0) and dimethyl acetylenedicarboxylate. Addition of unsymmetrical alkynes is regioselective and the regiochemistries of the adducts isolated from
