General description

XPhos Pd G2 is a bulky monodentate biaryl ligand. It is a Buchwald′s 2nd generation preformed catalyst. It undergoes rapid reductive elimination to form a reactive, monoligated Pd(0) species.

For larger scale uses, product also available in powdered form (741825)

Application

XPhos Pd G2 was employed as catalyst in the following reactions:
  • Palladium-catalyzed Suzuki-Miyaura coupling reactions of potassium organotrifluoroborates and sulfamates.
  • Suzuki-Miyaura cross-coupling reactions of sensitive aryl and heteroarylboronic acids.
  • Synthesis of potassium Boc-protected secondary aminomethyltrifluoroborates, via Suzuki-Miyaura cross-coupling reaction.
2nd Generation Buchwald Precatalysts
  • Widely used for Suzuki-Miyaura cross-coupling reactions
  • 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.
