Conversion of adducts formed from tricarbonyl(vinylketene)iron(0) complexes and alkynes into cyclopentenediones and phenols
Abstract
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.
