Descripción

Aplicación

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

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.
