Általános leírás

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.

Alkalmazás

Application Guide for Palladium Catalyzed Cross-Coupling Reactions

Used in the synthesis of semiconducting metal-containing polymers in which the polypyrrole backbone has a conformational energy minimum and is nearly planar.
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.

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.

Treatment of thiol esters 1 with zinc reagent 2 in the presence of a small amount (<ca. 1 mol %) of nonpyrophoric Pd(OH)(2)/C (Pearlman's catalyst) provided functionalized asymmetrical ketones 3 in high yields. The use of Pd(OH)(2)/C was further applied

A unique method was discovered to construct polysubstituted pyrroles via an unprecedented multiple deprotonations/deaminations process from commercially available phenethylamines. During this transformation, twelve bonds were broken and five new bonds were constructed.
