Description

t-BuXphos Palladacycle Gen. 4 delivers a sterically hindered, bench-stable palladium complex engineered for efficient cross-coupling under mild conditions. Featuring a robust xanthene-based ligand framework, it enables rapid activation and stable catalytic turnover in Suzuki-Miyaura and Negishi reactions. This catalyst excels in challenging substrates with poor reactivity, offering high functional group tolerance and minimal Pd leaching.

Application

t-BuXphos Palladacycle Gen. 4 serves as a highly effective precatalyst in palladium-catalyzed cross-coupling reactions, enabling efficient C–C and C–heteroatom bond formation under mild conditions. Its robust steric and electronic profile enhances catalyst longevity and turnover, particularly in challenging substrates. The ligand’s bench-stable nature and compatibility with diverse functional groups make it ideal for scalable synthesis and complex molecule assembly.
