Preparation of Bis(Triphenylphosphine)Palladium(II) Chloride:
Add 10g of triphenylphosphorus and 45g of water into a dry single-necked bottle, and stir the electromagnetically to make the system uniform; then add 3g of palladium chloride into the single-necked bottle at one time, stir and react at room temperature for 70min, observe that the material in the bottle gradually changes from black It turns into yellow-earth yellow until the black disappears, that is, the reaction is complete. After the reaction is complete, filter and vacuum dry the filter cake to obtain a yellow solid, which is bis(triphenylphosphonium) palladium dichloride, with a yield of 100%.
Bis(Triphenylphosphine)Palladium(II) Chloride Application:
Bis(triphenylphosphine) palladium chloride can be used as a catalyst for organic synthesis. It is mostly used in suzuki reaction. The carboxylic acid can be decarboxylated under the catalyst of catalytic amount of bis(triphenylphosphine) palladium chloride to form α-ene.
Bis(Triphenylphosphine)Palladium(II) Chloride Uses:
As a catalyst, used in coupling reactions such as Suzuki, Kumada, Negishi, etc. Uses are mainly used in coupling reactions such as Sonogoshira coupling; catalyst for carbonylation of halogenated substances; halogenated alkanes to aldehydes, carboxylic acids, amides, etc.; halogenated alkanes react with acetylene to form carbon Chain growth of alkyne compounds.
