MDL
MFCD00011167
EINECS
231-115-6

Propriétés chimiques

Formule
Pd
Solubilité
Insoluble in water and organic solvents.

Applications

It is a catalyst used in Stille reaction, hydrogenation reactions, Suzuki-Miyaura cross-coupling and Heck-Mizoroki reactions, deoxygenation, oxidation reactions and coupling reactions.

Notes

Palladium on carbon should always be handled under an inert atmosphere (preferably argon), and reaction vessels should be flushed with inert gas before the catalyst is added.

Références bibliographiques

General-purpose hydrogenation catalyst suitable for a wide variety of applications. For a monograph, see: P. N. Rylander, Hydrogenation Methods, Academic Press, N.Y. (1985).

A large number of examples of hydrogenation reactions can be found in Organic Syntheses, although some of the earlier procedures may be somewhat outdated. A selection of rather more recent examples employing palladium on carbon include:

Hydrogenation of alkene to alkane: Org. Synth. Coll., 5, 97 (1973). Reduction of nitro to amine: Org. Synth. Coll., 5, 829 (1973). Reductive alkylation of amines: Org. Synth. Coll., 5, 552 (1973). Reduction of azide to amine: Org. Synth. Coll., 5, 586 (1973). High-pressure reduction of furan rings tetrahydrofurans: Org. Synth. Coll., 6, 856 (1988).
