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.

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.

For small scale and high throughput uses, product is also available as ChemBeads (931055)

Scale-Up Guide: Buchwald-Hartwig Amination Reaction

All of the preformed catalysts used in the kit are air and moisture stable complexes in their commercially available form. Once activated by base under the reaction conditions they become sensitive to air. To best enable scale-up success, the use of standard Schlenk technique is recommended.
