Descripción general

BrettPhos Pd G4 is an N-substituted 2-aminobiphenylpalladium methanesulfonate precatalyst. It is a fourth generation (G4) Buchwald precatalyst that is similar to the third generation (G3) precatalysts except that the amino group on the biphenyl backbone is methylated. This modification helps to prevent the limitations of using the third generation precatalysts. It is air, moisture and thermally-stable and shows good solubility in common organic solvents. BrettPhos Pd G4 is highly useful in cross-coupling reactions. Some of its excellent features include lower catalyst loadings, shorter reaction time, efficient formation of the active catalytic species and accurate control of ligand: palladium ratio.

Artículos

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.

Contenido relacionado

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.
