General description

XantPhos 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. XantPhos Pd G3 is an excellent reagent for palladium catalyzed 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.

Application

XantPhos Pd G3 may be used in the following processes:
  • Negishi cross-coupling reaction during the synthesis of palmerolides.
  • Aminocarbonylation of heteroaryl bromides with carbon monoxide (CO) in the presence of triethylamine.
  • Coupling between polyglycosyl thiols and aglycon halides by C-S bond formation.
For small scale and high throughput uses, product is also available as ChemBeads (932213)

All of the preformed catalysts used in the kit are air and moisture stable complexes in their commercially available form. Once activated by base under the reaction conditions they become sensitive to air. To best enable scale-up success, the use of standard Schlenk technique is recommended.
