Palladium oxide is prepared by heating palladium sponge metal in oxygen at 350 °C. 2 Pd + O 2 → 2 PdO. The oxide is obtained as a black powder. The oxide also may be prepared specially for catalytic use by heating variously a mixture of palladium(II) chloride and potassium nitrate, 2 PdCl 2 + 4 KNO 3 → 2 PdO + 4 KCl + 4 NO 2 + O 2 ...
Palladium heated to 800 °C will produce a layer of palladium(II) oxide (PdO). It may slowly develop a slight brownish coloration over time, likely due to the formation of a surface layer of its monoxide. Palladium films with defects produced by alpha particle bombardment at low temperature exhibit superconductivity having T c = 3.2 K. [12]
Palladium(II) acetate, Pd(OAc) 2. Most ionic compounds of palladium involve the Pd 2+ oxidation state. Palladium(II) chloride is a starting point in the synthesis of other palladium compounds and complexes. [1] Palladium(II) acetate plus triphenylphosphine is used as a catalyst in organic synthesis.

Organopalladium chemistry is a branch of organometallic chemistry that deals with organic palladium compounds and their reactions. Palladium is often used as a catalyst in the reduction of alkenes and alkynes with hydrogen. This process involves the formation of a palladium-carbon covalent bond.

Palladium(II) acetate is a chemical compound of palladium described by the formula [Pd(O 2 CCH 3) 2] n, abbreviated [Pd(OAc) 2] n. It is more reactive than the analogous platinum compound . Depending on the value of n, the compound is soluble in many organic solvents and is commonly used as a catalyst for organic reactions.
In chemistry, compounds of palladium(III) feature the noble metal palladium in the unusual +3 oxidation state (in most of its compounds, palladium has the oxidation state II). Compounds of Pd(III) occur in mononuclear and dinuclear forms. Palladium(III) is most often invoked, not observed in mechanistic organometallic chemistry. [1] [2]
