General description

tBuDavePhos Pd G4 is a fourth generation (G4) 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. tBuDavePhos Pd G4 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.


tBuDavePhos Pd G4 will be used for a variety of C-C and C-N cross-coupling reactions.
