General description

BrettPhos 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. BrettPhos Pd G3 is an excellent reagent for Buchwald-Hartwig cross-coupling reaction. 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

BrettPhos Pd G3 may be used for the C-N coupling reaction between monosubstituted ureas and 1,2 dihaloaromatic system to form benzimidazolones.
It may be used in the synthesis of following compounds:
  • [Pd(cinnamyl)(BrettPhos)]OTf by reacting with [(cinnamyl)PdCl]2 and AgOTf.
  • [Pd(crotyl)(BrettPhos)]OTf by reacting with [(crotyl)PdCl]2 and AgOTf.
  • [Pd(allyl)(BrettPhos)]OTf by reacting with [(allyl)PdCl]2 and AgOTf.
  • Pd(allyl)(BrettPhos)Clby reacting with [(allyl)PdCl]2.
For small scale and high throughput uses, product is also available as ChemBeads (928321)

Buchwald Group – Professor Product Portal

The Buchwald group has developed a series of highly active and versatile palladium precatalysts and biarylphosphine ligands used in cross-coupling reactions for the formation of C-C, C–N, C–O, C–F, C–CF3, and C–S bonds. The ligands are electron-rich, and highly tunable to provide catalyst systems with a diverse scope, high stability and reactivity. Furthermore, the new series of precatalysts are air-, moisture and thermally-stable and display good solubility in common organic solvents. The use of precatalysts ensures the efficient generation of the active catalytic species and allows one to accurately adjust the ligand:palladium ratio. The ligands, precatalysts and methodology developed in the Buchwald group are user friendly and have rendered previously difficult cross couplings reactions, much easier to achieve.
