Application

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)

Features and Benefits

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

Safety Information

• Storage Class Code: 11 - Combustible Solids
• WGK: nwg
• Flash Point(F): Not applicable
