Buchwald Phosphine Ligands for chemical Synthesis
BrettPhos is a dialkylbiaryl phosphine ligand developed by the Buchwald group. It promotes cross-coupling reactions more efficiently and exhibits improved reactivity compared to other catalytic systems.
It can be used in:
  • palladium-catalyzed trifluoromethylation of aryl chlorides
  • Buchwald-Hartwig amination
  • synthesis of 4-aryl and alkyl substituted, N6-alkylated pyridazine-3,6-diamines via a Buchwald protocol
For small scale and high throughput uses, product is also available as ChemBeads (928348)

Características y beneficios

  • White crystalline solid
  • Air- and moisture-stable
  • Thermally stable
  • Highly efficient
  • Wide functional group tolerance
  • Excellent selectivity and conversion

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.
