Description générale

AdBrettPhos is a phosphine-based ligand used in the direct monoarylation of ammonia and suppresses diarylation. In addition, it is a good ligand for five-membered heteroarene couplings and is employed in the preparation of phosphine-ligated palladium complexes to facilitate C-N coupling reactions.

Application

AdBrettPhos can be used as an effective ligand for synthesizing [(L·Pd)n ·(1,5-cyclooctadiene)] pre-catalyst that can be used for the Pd-catalyzed fluorination of aryl triflates.

AdBrettPhos has been used in the Palladium-Catalyzed C-O Cross-Coupling of Primary Alcohols.

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.
