Abstract
Reaction between chlorotrifluoroethylene and the anions [Re(CO)5]– and [π-C5H5·Fe(CO)2]– gives σ-perfluorovinyl–metal complexes; the weaker nucleophile [Mn(CO)5]– adds to the olefin affording HCCIF·CF2·Mn(CO)5. All three anions react with 1,2-dichlorohexafluorocyclopentene, giving complexes in which the metal has replaced one of the chlorine atoms. With 1,2-dichlorohexafluorocyclobutane, elimination of both chlorine atoms occurs, the resulting perfluorocyclobutene reacting further to give small amounts of the previously reported σ-perfluorocyclobutenylmetal complexes. Treatment of chloromercuriferrocene with [Re(CO)5]– gives diferrocenylmercury, mercury, and pentacarbonyl(chloro)rhenium.Keywords
