Beschreibung

Allgemeine Beschreibung

QPhos 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. QPhos Pd G3 is an excellent reagent for palladium catalyzed cross-coupling reactions. 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.

Anwendung

QPhos Pd G3 has been used as a precatalyst for the arylboration of isoprene with regioselectivity. It may also be used for a variety of aminination and etherifications of aryl halides.
