General description

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.

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.

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
