General description

Palladium(II)acetate, recrystallized, is commonly used as a catalyst in cross-coupling reactions. Prominent applications include the Buchwald-Hartwigamination reaction, Heck reaction, Suzuki coupling, Stille coupling, Sonogashira coupling, and Negishi coupling reactions.

Application

Palladium(II) acetate, recrystallized can be used as a catalyst:
  • In Stille cross-coupling reaction between benzylic halides and aryl tributyltin to synthesize diarylmethane derivatives in the presence of phosphine ligand.
  • For the α-arylation of ketones with aryl halides to synthesize arylmethyl ketones in the presence of n-butylbis(1-adamantyl)-phosphine ligand.
  • In Suzuki-Miyaura cross-coupling reaction between aryl bromides and aryl boronic acids to synthesize biaryl derivatives in the presence of phosphane ligand.
  • In Buchwald-Hartwig amination reaction between aryl chlorides and anilines to synthesize arylated anilines in the presence of N-heterocyclic carbene ligand.

Non-aromatic nitrogen- and oxygen-containing heterocycles such as piperidines and pyrans are prevalent components of natural products and pharmaceutical drugs. Although it has been a workhorse as a synthetic method for assembling unsaturated sp(2)-hybridized substrates, transition metal-catalysed cross-coupling chemistry is traditionally
