Descripción

General description

Palladium(II) chloride (PdCl₂) reacts with unsubstituted or alkyl-substituted cyclic ketones in the CO atmosphere to afford acyclic diesters and acyclic chloro-substituted monoesters. PdCl₂ reacts with N,N-dimethylallylamine in methanol to afford di-μ-chloro-bis(2-methoxy-3-N,N-dimethylaminopropyl)dipalladium(II). Palladium dichloride, acetate and acetylacetonate in the [bmim][BF₄] or [bmim][PF₆] (where[bmim]⁺ = 1-butyl-3-methylimidazolium cation) ionic liquids have been employed for the hydrodimerization of butadiene to form octa-2,7-dien-1-ol.

Palladium(II) chloride is used as an oxidizing agent and catalyst for the Suzuki-Miyaura and Mizoroki-Heck reactions.

Application

Guía de aplicaciones para las reacciones de acoplamiento transversal catalizadas por paladio

Utilizado en la síntesis de polímeros que contengan metales semiconductores en los cuales el esqueleto polipirrólico tiene una mínima energía conformacional y es casi plana.

Palladium(II) chloride (PdCl₂) was used in the following studies:

• As catalyst for the carbonylation of organic tellurides by reaction with carbon monoxide.
• As a catalyst along with Cu(II) for the deamination of phenethylamines to phenyl substituted pyrroles.
• Together with PEG 300, promoted efficient Suzuki-coupling of aryl chlorides with aryl boronic acids.

For small scale and high throughput uses, product is also available as ChemBeads (919853)
