Descrizione

Descrizione generale

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.[1] PdCl₂ reacts with N,N-dimethylallylamine in methanol to afford di-μ-chloro-bis(2-methoxy-3-N,N-dimethylaminopropyl)dipalladium(II).[2] 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.[3]

Palladium(II) chloride is used as an oxidizing agent[4] and catalyst for the Suzuki-Miyaura[5] and Mizoroki-Heck reactions.[6]

Applicazioni

Guida applicativa per le reazioni di accoppiamento incrociato catalizzate dal palladio

Utilizzato nella sintesi dei polimeri contenenti metalli semiconduttori in cui lo scheletro di polipirrolo presenta una minima energia conformazionale ed è quasi planare.

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

• As catalyst for the carbonylation of organic tellurides by reaction with carbon monoxide.[7]
• As a catalyst along with Cu(II) for the deamination of phenethylamines to phenyl substituted pyrroles.[8]
• Together with PEG 300, promoted efficient Suzuki-coupling of aryl chlorides with aryl boronic acids.[9]

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