The largest use of palladium today is in catalytic converters. [41] Palladium is also used in jewelry, dentistry, [41] [42] watch making, blood sugar test strips, aircraft spark plugs, surgical instruments, and electrical contacts. [43] Palladium is also used to make some professional transverse (concert or classical) flutes. [44]
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.
More examples of substrate-controlled, anti-Markovnikov Tsuji-Wacker Oxidation of olefins are given in reviews by Namboothiri, [40] Feringa, [36] and Muzart. [41] Grubbs and co-workers paved way for anti-Markovnikov oxidation of stereoelectronically unbiased terminal olefins, through the use of palladium-nitrite system (Figure 2, D). [42]
Although both have industrial uses, they are better known for their uses in art, jewelry, and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded. [1]
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.
The compound Pd 2 (dba) 3 is a source of Pd(0), which is the catalytically active source of palladium used for many reactions, including cross coupling reactions. [4] Pd2(dba)3 was thought to be a homogeneous catalytic precursor, but recent articles suggest that palladium nanoparticles are formed, making it a heterogeneous catalytic precursor. [4]
Palladium on carbon is used for catalytic hydrogenations in organic synthesis. Examples include reductive amination, [2] carbonyl reduction, nitro compound reduction, [3] [4] the reduction of imines and Schiff bases [1] and debenzylation reactions.
