Abstract

Photochemical reactions of the dinitrogen complex Cp*Re(CO)2N2 with tetrachloroethylene and trichloroethylene yield the coordination complexes Cp*Re(CO)2(η2-tetrachloroethy lene) (1) and Cp*Re(CO)2(η2-trichloroethyle ne) (2), respectively. Complex 1 reacts thermally in polar organic solvents to produce the C-Cl bond activation product cis-Cp*Re(CO)2(C2Cl3)C l (3). All complexes were isolated and characterized by IR, 1H and 13C NMR spectroscopies and mass spectrometry. Complex 3 was also characterized by X-ray crystallography. © 2006 Elsevier B.V.
