DyadPalladate鈩� precatalysts

Johnson Matthey鈥檚 DyadPalladate鈩� precatalysts are a series of bisphosphonium dichloropalladate complexes featuring tertiary phosphonium ligands that are effective catalysts for Suzuki-Miyaura cross-coupling reactions and Buchwald-Hartwig aminations of (hetero)aryl halides. Our portfolio currently contains a range of DyadPalladate鈩� precatalysts featuring seven Buchwald-type ligands for various cross-coupling reactions. 
 

Advantages of bisphosphonium dichloropalladate complexes:

  • Reduced process costs associated with catalyst contributions.
  • Simple, scalable, efficient and much more rapid synthesis.
  • Similar reactivity to other precatalysts, while still providing air and moisture stability, and often enhanced reactivity compared to in situ systems.
