Description générale

Josiphos SL-J009-1 Pd G3 (Josiphos SL-J009-1-G3-palladacycle) is a modified G3 precatalyst (G3′). It has been synthesized by Buchwald and coworkers from second generation (G2) precatalyst by methylation of the amino group present on biphenyl backbone. It is a useful catalyst for various cross-coupling reactions. G3 precatalysts are versatile catalysts. They have long life in solution and are readily soluble in various organic solvents. G3- precatalysts have been employed in various C-N bond forming reactions.

Articles

Preformed catalysts in the kit are stable but become air-sensitive when activated; Schlenk technique aids scale-up.

All contents in the foil bag are weighed, plated, packed, and sealed in a glove box under nitrogen.

G3 and G4 Buchwald palladium precatalysts are the newest air, moisture, and thermally stable crossing-coupling complexes used in bond formation for their versatility and high reactivity.
