Palladium acetylacetonate is the palladium salt of acetylacetone. Palladium is a chemical element with the chemical symbol Pd and an atomic number of 46. It is found as a free metal alloyed with gold and other platinum group metals and in the rare minerals cooperite and polarite.
Palladium may be absorbed through oral, dermal, and inhalation exposure. Once in the body it distributes to the kidney, liver, spleen, lymph nodes, adrenal gland, lung and bone. Palladium's ability to form complexes allows it the bind to amino acids, proteins, DNA, and other macromolecules. Palladium and its metabolites are excreted in the urine and faeces.
Acetylacetone is a versatile bifunctional precursor to heterocycles because both keto groups undergo condensation. Hydrazine reacts to produce pyrazoles. Urea gives pyrimidines. Condensation with aryl- and alkylamines to gives the mono- and then the didiketimines wherein the O atoms in acetylacetone are replaced by NR (R = aryl, alkyl).
