    • Oligo and polyuronic acids interactions with hypervalent chromium 
      González, J. C.; García, S. I.; Bellú, Sebastián; Atria Salas, Ana María; Salas Pelegrin, Juan Manuel; Rockenbauer, A.; Korecz, L.; Signorella, Sandra; Sala, Luis F. (PERGAMON-ELSEVIER SCIENCE LTD, 2009-09-02)
      Selective oxidation of galacturonic residues of oligo and polyuronic acids by Cr-VI affords CO2/HCO2H, oxidized uronic acid, and Cr-III as final redox products. Kinetic studies show that the redox reaction proceeds through ...
    • Redox and complexation chemistry of the CrVI/CrV–d-galacturonic acid system 
      González, Juan; Daier, Verónica; García, Silvia; Goodman, Bernard; Atria Salas, Ana María; Sala, Luis; Signorella, Sandra (2004)
      The oxidation of D-galacturonic acid by Cr-VI yields the aldaric acid and Cr-III as final products when a 30-times or higher excess of the uronic acid over Cr-VI is used. The redox reaction involves the formation of ...
