General description

GPhos is a Buchwald-type ligand used in various cross-coupling reactions.

Application

GPhos is a dialkylbiaryl monophosphine ligand developed by the Buchwald group for aryl amination reactions. The GPhos Pd oxidative addition complex (OAC) enables room temperature C-N couplings with complex substrates at higher efficiency than previously developed ligands.

For general uses, product is also available in powdered form (918008)

Features and Benefits

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.

High-throughput experimentation (HTE) methods are central to modern medicinal chemistry. While many HTE approaches to C-N and Csp2 -Csp2 bonds are available, options for Csp2 -Csp3 bonds are limited. We report here how the adaptation of nickel-catalyzed cross-electrophile coupling of
