Photochemical, thermal and spectroscopic studies of metal carbonyl complexes

Creaven, Bernadette (1989) Photochemical, thermal and spectroscopic studies of metal carbonyl complexes. PhD thesis, Dublin City University.

Flash photolysis of CpMn(C0)3, CbFe(C0)3 and ArCr(C0)3 in alkane solvents, resulted m the immediate formation of the solvent substituted dicarbonyl species. The reactivity of these species were investigated by uv/vis flash photolysis studies and in the case of CpMn(C0)3 by tnr flash photolysis. The rate constants for the reaction of theses species with a variety of nucleophiles were determined and the thermodynamic parameters associated with these reactions were measured. The chelation reactions of chromium carbonyl complexes, containing multidentate ligands, were investigated by uv/vis and ir spectroscopy. These chelation reaction were seen to proceed via bridging intermediates, even in those cases where the initial complex was coordinated in a monodentate fashion. The crystal structures of a number of chromium and tungsten complexes were determined and correlated with their spectroscopic features.
