Infrared and nuclear magnetic resonance spectra of palladium (II) monothio-β-diketonates were studied in comparison with those of palladium (II)β-diketonates. The following novel reactions have been found. Namely, palladium dithioacetylacetonate was obtained in the reaction of monothioacetylacetone and palladium ion in acid solution by the reaction which may be called as “ligand atom replacement reaction” and palladium monothio-β-diketonates were obtained from disulfides of monothio-β-diketones and palladium ion. The reason for the occurance of this reaction may be reasonably explained by the high affinity between palladium and sulfur and the high stability of the palladium chelates formed.
