Palladium is also a versatile metal for homogeneous catalysis, used in combination with a broad variety of ligands for highly selective chemical transformations. In 2010 the Nobel Prize in Chemistry was awarded "for palladium-catalyzed cross couplings in organic synthesis" to Richard F. Heck, Ei-ichi Negishi and Akira Suzuki.
Palladium compounds. Palladium forms a variety of ionic, coordination, and organopalladium compounds, typically with oxidation state Pd 0 or Pd 2+. Palladium (III) compounds have also been reported. Palladium compounds are frequently used as catalysts in cross-coupling reactions such as the Sonogashira coupling and Suzuki reaction.
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 is also prominent in carbon-carbon ...
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]
view. talk. edit. Natural palladium (46 Pd) is composed of six stable isotopes, 102 Pd, 104 Pd, 105 Pd, 106 Pd, 108 Pd, and 110 Pd, although 102 Pd and 110 Pd are theoretically unstable. The most stable radioisotopes are 107 Pd with a half-life of 6.5 million years, 103 Pd with a half-life of 17 days, and 100 Pd with a half-life of 3.63 days.
The Stille reaction is a chemical reaction widely used in organic synthesis. The reaction involves the coupling of two organic groups, one of which is carried as an organotin compound (also known as organostannanes). A variety of organic electrophiles provide the other coupling partner. The Stille reaction is one of many palladium-catalyzed ...
The platinum-group metals (PGMs), also known as the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs), are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 ...
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.
