PEREZ, F. R.; BASAEZ, L.; BELMAR, J.  y  VANYSEK, P.. CYCLIC VOLTAMMETRY OF 1-(n-HEXYL)-3-METHYL-5-PYRAZOLONE-BASED ENAMINES AND THEIR CHLOROMANGANESE(III) AND NITRIDOMANGANESE(V) COMPLEXES. J. Chil. Chem. Soc. [online]. 2005, vol.50, n.3, pp. 575-580. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072005000300009.

In this publication we are reporting for the first time on examples of the redox behavior of enamines and complexes derived from 1-alkylpyrazolones. Cyclic voltammetry experiment was performed on three enamines derived from 4-acyl-1-(n-hexyl)-3-methylpyrazol-5-ol and their chloromanganese(III) and nitridomanganese(V) complexes. The ligands have an irreversible oxidation potential of 1.1 V. Chloromanganese(III) complexes are quasi-reversible with an E1/2 of ­ 0.1 V. Nitridomanganese(V) complexes are also quasi-reversible, with E1/2 potentials of 0.95 V. However, for nitridomanganese(V) complexes reversibility increases as the scan speed raises from 100 to 3000 mV·s-1
