Notes:
The mass spectra of the title compounds have been determined and special attention has been given to metastable transitions and ion composition assignments. The interpretation of the mass spectra of N,N'-ethylenebis(5,5,5-trifluoro-4-oxopentan-2-imine) and its metal complexes is relatively straightforward. Bond breaking α and β (with H transfers) to nitrogen in the ethylenediamine portion of the molecule overwhemingly dominates the spectra. Changing the diamine bridge adds new features to the spectra in both expected and unexpected ways. Ligand fragmentation changes little when complexed to nickel as compared to hydrogen. Chelation of Cu(II) on the other hand leads to new fragmentation channels which increase in importance as electron availability in the diamine bridge increases. These new reactions are attributed to a reduction of the copper centre in the molecule.
