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 these reactions were determined by X-ray crystal structure analyses of the products from but-3-yn-2-one and tricarbonyl(3-tert-butyl-5-phenyl-1-oxapenta-1,2,4-triene)iron(0), and of the structurally modified product derived from diethylpropynylamine and tricarbonyl(5-phenyl-3-iso-propyl-1-oxapenta-1,2,4-triene)iron(0).Thermolysis of the adducts leads to either cyclopentenediones or phenols and its outcome is dependent on the electronic properties of the carbon-1 substituent of the adduct.The phenols may be synthesised directly and regioselectively from tricarbonyl(vinylketene)iron(0) complexes and the appropriate alkynes.
Conversion of Adducts formed from Tricarbonyl(vinylketene)iron(0) Complexes and Alkynes into Cyclopentenediones and Phenols

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 synt
