Description

Application

tBuXPhos Pd G3 may be used to synthesize 4-cyano-7-azaindole from 4-chloro-7-azaindole by cyanation reaction. It may also be used for the α-arylation reaction of acetate esters at room temperature.

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.

General description

tBuXPhos Pd G3 is a third generation (G3) Buchwald precatalyst. It is air, moisture and thermally-stable and is highly soluble in a wide range of common organic solvents. It has long life in solutions. tBuXPhos Pd G3 is an excellent reagent for Buchwald-Hartwig cross-coupling reaction. Some of its unique features include lower catalyst loadings, shorter reaction time, efficient formation of the active catalytic species and accurate control of ligand: palladium ratio.

For larger scale uses, product also available in powdered form (762229)
