Hot Sale Bis(triphenylphosphine) Palladium (II) Chloride

Details:

Palladium dichloride, insoluble in water. Soluble in toluene, benzene, slightly soluble in acetone, chloroform. Melting point is 260 degrees Celsius, as a catalyst, it is mainly used for SonogChemicalbookoshira coupling reaction and other coupling reactions, halogenated carbonylation catalyst, halogenated alkanes to aldehydes, carboxylic acids, amides, etc., halogenated alkanes react with acetylene into carbon chain growth alkyne compounds.

As a catalyst, it is used in coupling reactions such as Suzuki, Kumada and Negishi. Because of its palladium content, dichloride (triphenylphosphine) palladium (II) is mainly used in organometallic catalytic reactions. It also participates in the crystalline structure of metal ring complexes, showing anti-inflammatory and antifungal properties.

Production methodprocess:Methods a four chlorine put excess acid potassium and potassium chloride together in three benzene 'b? The alcohol solution is heated, then sodium chloride is filtered out, the solvent is steamed, and the residue is washed with water, alcohol, and pentane in turn. The residue is recrystallized in hot trichloromethane to get pure product. Method two: 1 gram of Chemicalbook benzylin hot ethanol solution, 0.55 gram of tetrachloride acid and 10 ml of ethanol were mixed together to shake, and yellow solid was immediately precipitated. Add 50 ml of water and continue oscillating. Filtration, drying, recrystallization in toluene to produce bright yellow crystals. It is insoluble in hot ethanol and acetone.
