The pseudo-aromatic divalent palladium acetylacetonate has been found to undergo electrophilic substitution at the central carbon of the chelate ring. The mononitro (decomp.p. 240–245°C, λmax 325 mμ) and dinitro (decomp.p. 250–255°C, λmax 324 mμ) palladium acetylacetonates were prepared by treating palladium acetylacetonate with a mixture of copper nitrate trihydrate and acetic anhydride; they were characterized by their infrared and NMR spectra. The halogenation of palladium acetylacetonate was accomplished with N-halosuccinimides in chloroform. Dichloro (decomp.p. 205–210°C, λmax 345 mμ), dibromo (decomp.p. 240–245°C, λmax 345 mμ) and diiodo (decomp.p. 195–200°C, λmax 324 mμ) derivatives were isolated and characterized by their spectra.
