General description
tBuSPhos [2-ditertbutylphosphino-2′,6′-dimethoxybiphenyl] is an electron-rich biaryl phosphine ligand developed by the Buchwald group to enhance the reactivity of palladium catalysis during cross-coupling reaction.
Application
tBuSPhos has been used in:
- The Pd catalyzed amination of hindered aryl halides with 9H-carbazole [1]
- The chemoselective Suzuki coupling of aryl chlorides bearing cidic functional groups.[2]
- The synthesis of gold(I) carbenes from chloro(mesityl)methylgold(I) carbenoids bearing Buchwald-type ligands.
Features and Benefits
The palladium complexes of tBuSPhos exhibit high activity for Suzuki coupling reactions involving aryl chlorides, which are unreactive with palladium complexes of many other phosphine ligands.
