General description

rac-BINAP-Pd-G3 is a third generation (G3) Buchwald precatalyst. t is air, moisture and thermally-stable and is highly soluble in a wide range of common organic solvents. It has long life in solutions. rac-BINAP-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. It

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.

Související obsah

The Buchwald group has developed a series of highly active and versatile palladium precatalysts and biarylphosphine ligands used in cross-coupling reactions for the formation of C-C, C–N, C–O, C–F, C–CF3, and C–S bonds. The ligands are electron-rich, and highly tunable to provide catalyst systems with a diverse scope, high stability and reactivity. Furthermore, the new series of precatalysts are air-, moisture and thermally-stable and display good solubility in common organic solvents. The use of precatalysts ensures the efficient generation of the active catalytic species and allows one to accurately adjust the ligand:palladium ratio. The ligands, precatalysts and methodology developed in the Buchwald group are user friendly and have rendered previously difficult cross couplings reactions, much easier to achieve.
