The Polarographic Reduction of [Pd(oxine)2] and [Pd(acac)2] in a N , N -Dimethylformamide Solution

Abstract

Palladium(I) species were produced by the polarographic reduction of palladium(II)–oxinate and –acetylacetonate complexes in a N,N-dimethylformamide solution. These species were unstable and decomposed into electro-inactive species through an irreversible following chemical reaction. The rate constants were obtained from the fundamental and second harmonic AC polarograms, which were obtained at two different frequencies of the AC potential, 55.8 and 173.6 Hz, at 22.5 °C as 5.5±1.0 s−1 for the oxinate complex and as 50±10 s−1 for the acetylacetonate complex.
