Application

Application Guide for Palladium Catalyzed Cross-Coupling Reactions
Allylpalladium(II) chloride dimer has been employed for the following studies:
  • Synthesis of cationic palladium cataysts, used in the microwave-assisted Heck arylation.
  • Synthesis of N-heterocyclic carbene-palladium-η3-allyl chloride complexes, which are efficient catalyst for the Suzuki-Miyaura cross-coupling of aryl bromides and activated aryl chlorides.
  • Synthesis of 1,4-diallyl-1,2-dihydroisoquinolines.
  • As catalyst for greener Buchwald-Hartwig coupling in TPGS-750-M.

A Pd/N-heterocyclic carbene-based catalyst achieves the Sonogashira coupling of an array of functionalized, beta-hydrogen-containing alkyl bromides and iodides under mild conditions. By furnishing the first example of a nonphosphine-based palladium catalyst for cross-coupling unactivated alkyl electrophiles, this study provides an
