Abstract
The tricarbonyl(vinylketene)iron(o) complex 6 reacted with dimethyl maleate, dimethyl fumarate, (E)-methyl 4-oxopent-2-enoate and (E)-ethyl 4,4,4-trifluorobut-2-enoate to give decarbonylated adducts 7-10 respectively. An X-ray crystal structure analysis of the adduct 7, formed from the complex 6 and dimethyl maleate, and a mechanistic explanation for the formation of the adducts are presented. Oxidation of the adducts. 7-10 using (NH4)(2)Ce(NO3)(6) gave a range of organic products including the tetrasubstituted cyclopropanes 20 and 23-25, the cyclobutane-1,2-dione 22, the trisubstituted lactone 21 and the alpha,beta-unsaturated ketone 26.
