Palladium, 10% on carbon, Type 487, dry

MDL
MFCD00011167
EINECS
231-115-6

Proprietà chimiche

Solubilità
Insoluble in water and organic solvents.

Applicazioni

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

Note

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.

Letteratura

Hydrogenation catalyst, which may be preferred where deactivation by the reaction products is possible:

Used in low-pressure hydrogenolysis of N-benzylamines: Org. Synth. Coll., 7, 152 (1990). Reduction of oximes to amines: Org. Synth. Coll., 5, 376 (1973). Widely used along with hydrogen donors such as Ammonium formate, A10699, Sodium formate, A17813, Formic acid, A13285, Cyclohexene, A11359, or Hydrazine monohydrate, A14005, for catalytic transfer hydrogenation reactions. In combination with Sodium borohydride, 13432, promotes the reduction of nitro-compounds to amines, where borohydride alone is ineffective: Synthesis, 713 (1987).
