General description

XPhos Pd G3 is a third generation (G3) Buchwald precatalyst. It is air, moisture and thermally-stable and is highly soluble in a wide range of common organic solvents. It has long life in solutions. XPhos Pd G3 is an excellent reagent for Suzuki cross-coupling reactions. Some of its unique features include lower catalyst loadings, shorter reaction time, efficient formation of the active catalytic species and accurate control of ligand: palladium ratio.

For larger scale uses, product also available in powdered form (763381)

Application

XPhos Pd G3 may be used in the following reactions:
  • Cyanation reaction of heterocyclic halides.
  • Coupling of heteroaryl chlorides with polyfluoroaryl zinc reagents.
  • Coupling of 2,6-difluorophenylboronic acid with (hetero)aryl chlorides.
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.
