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.
Contenuto correlato
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.
Explore reliable, premium grade catalysis materials for your pharma or industrial project. Specialty chemicals and formulations are available in bulk quantities and volumes from a few grams to multi-metric tons with complete documentation to simplify your leap from development to commercialization.
