Description
TrixiePhos is a bench-stable, electron-rich phosphine ligand featuring a sterically shielded aryl backbone that enhances catalyst longevity. This ligand integrates seamlessly into palladium-catalyzed cross-coupling reactions, delivering high yields under standard conditions. Its moisture-tolerant character simplifies handling in air-sensitive workflows.
Application
TrixiePhos serves as a highly efficient, bench-stable phosphine ligand for palladium-catalyzed cross-coupling reactions. Its tridentate architecture enhances catalyst stability and turnover, enabling reliable coupling of challenging substrates such as sterically hindered aryl chlorides and heteroaryl halides. The ligand demonstrates excellent functional group tolerance and facilitates straightforward purification, making it well-suited for iterative synthesis in medicinal chemistry and process development workflows.
