    • Complexation of amino sugars with cobalt(III) bis (phenanthroline) 
      Bunel Torrealba, Sergio; Ibarra, Carmen; Moraga, Exequiel; Parada Aliste, José; Blasko, Andrei; Whiddon, Christy; Bunton, Clifford A. (Elsevier, 1998)
      The I3- salts soluble in acetone and sparingly so in methanol, and I3- inhibits formation of Co(II) so that minor decomposition of acomplex does not broaden its 1H NMR signals. The (phen)2 complex of Co(III) with D-glucosamine ...
    • Complexation of mannosamine with cobalt(III) bis-phenanthroline. Isolation of a stable triiodide salt 
      Bunel Torrealba, Sergio; Ibarra, Carmen; Moraga, Exequiel; Parada Aliste, José; Blasko, Andrei; Bunton, Clifford A. (Sociedad Chilena de Química, 1997)
      D-β-Mannosamine reacts with cobalt(III) bis-phenanthroline to form a single 1:1 complex with the ∆ configuration at Co(III) which can be isolated as the stable triiodide salt.
    • Mixed complexes of cobalt(III) with D-glucosamine and phenanthroline 
      Blasko, Andrei; Bunton, Clifford A.; Bunel Torrealba, Sergio; Moraga, Exequiel; Ibarra, Carmen; Parada Aliste, José (Sociedad Chilena de Química, 1995)
      Examination of 1H chemical shifts of a complex of D-glucosamine with bis-phenanthroline cobalt(III)shows that the dominant ∆-complex is formed from α-D-glucosamine. A molecular mechanics simulation of the structure of ...
    • Structures of complexes of cobalt(III) and glucosamine. Applications of molecular mechanics and NMR spectroscopy 
      Bunel Torrealba, Sergio; Ibarra, Carmen; Moraga, Exequiel; Blasko, Andrei; Bunton, Clifford A. (Elsevier Science Publishers B.V., 1993)
      The 1H NMR signals of the hydrochlorides of 2-amino-2-deoxy-α and β -D-Glucose (α-and β-D-glucosamine) have been assigned and chemical shifts and coupling constants determined from their phase-sensitive COSY spectra in ...
