    Novel Nitrido- and Oxo(phthalocyaninato) Complexes of Molybdenum, Tungsten and Rhenium (2000)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 2000 (2000), S. 1025-1030 
    Details
    ISSN: 1434-1948
    Keywords: Phthalocyanines ; Nitrides ; Oxo complexes ; Rhenium ; Molybdenum ; Tungsten ; Chemistry ; General Chemistry

    Topics: Chemistry and Pharmacology
    Notes: The synthesis of new nitrido(phthalocyaninato)molybdenum (1-4) and -tungsten complexes (5-7) starting from the corresponding phthalonitriles and MNCl3 (M = Mo, W) is reported. In addition, the reaction of (tBu4Pc)WN (6) with PPh3 leading, after several steps, to the diamagnetic compound (tBu4Pc)WO (7) is described. The reaction of (tBu4Pc)ReN (9) with PPh3 leads to [(tBu4Pc)ReO]2 (12), and of [(C5H11)8Pc]ReN (10) with PPh3 leads, under different conditions, to {[(C5H11)8Pc]ReO}2O (11).

    Stability and Polymerization of uranyl-catechol chelates (1968)
    New York, NY : Wiley-Blackwell
    Journal für Praktische Chemie/Chemiker-Zeitung 38 (1968), S. 280-288 
    Details
    ISSN: 0021-8383
    Keywords: Chemistry ; Organic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: Interaction of uranyl ions with catechol has been investigated by the potentiometric and spectrophotometric techniques. Potentiometric titrations of uranyl nitrate with caustic potash in presence of catechol exhibited a sharp inflexion at 2⅔ moles of alkali der mole of the metal ion. At the initial stages of the titration, the reaction was shown to proceed as: \documentclass{article}\pagestyle{empty}\begin{document}$$ \rm{UO}_2^{2 + } + \rm{C}_6 \rm{H}_4 \left({\rm{OH}} \right)_2 \rightleftharpoons \rm{UO}_2 \rm{C}_6 \rm{H}_4 \rm{O}_2 + 2\rm{H}^ + . $$\end{document} The equilibrium constant of the reaction was found to be 2.88 · 10-7 giving a value of 3.87·1014 for the formation constant of the chelate. Equilibrium constant of the reaction: \documentclass{article}\pagestyle{empty}\begin{document}$$ \rm{2UO}_2^{2 + } + 2\rm{H}_2 \rm{A} \rightleftharpoons \left({\rm{UO}_2 \rm{A}_2 } \right)_{\rm2} + 4\rm{H}^ + . $$\end{document} has been found to be 1.00·10-10. The binuclear chelate species have been found to polymerize further through hydrolytic reactions.
