Application

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

Features and Benefits

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