Abstract

Oxidation of the adducts formed from tricarbonyl (vinylketene) iron(o) complexes and alkynes by iron(lll) chloride in methanol/water leads to the replacement of the tricarbonyliron(o) unit with an oxygen atom derived from the water. This pathway to furan-3(2H)-ones requires the presence of an electron-withdrawing substituent on carbon-2 of the vinylketene-alkyne adduct. Data used to assign the structures of some of the vinylketene-alkyne adducts used in this study included an X-ray crystal structure analysis of the unusual lactone complex 5c.
