    Synthesis of Oligomeric and Polymeric Ethers Containing the Cp*Ru+ and CpFe+ Metal Moieties (2000)

    Notes: Abstract A variety of homometallic (Cp*Ru+) and heterometallic (CpFe+–Cp*Ru+) oligomers with one to five metal moieties were prepared in high yields (74–90%) via nucleophilic aromatic substitution reactions. For the mixed metal systems, it is shown that the arrangement of the metal moieties along the backbone can be controlled. In addition, the synthesis of heterometallic polymers is described, along with their decomplexation and thermal properties. It was found that the thermal properties and solubility of the systems are greatly dependent on the linkages within the polymer backbone.

    Notes: [Auszug] IT was shown recently1 that under specified cultural conditions the whole of the antibacterial activity of metabolism solutions from Aspergillus effusus Tiraboschi can be attributed to kojic acid. It was suggested that this common mould metabolic product might similarly account ...

    The mass spectra of metal complexes of dibenzoylmethane (1968)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 1 (1968), S. 115-126

    ISSN: 0030-493X
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The mass spectra of a series of metal complexes of dibenzoylmethane have been rationalized. The paths of novel rearrangement reactions involving both hydrogen and oxygen migration may differ according to the type of metal atom in the complex. Further examples are proposed of the effect of metal valency changes in ion reactions.
