Application

cataCXium® A or di-adamantylalkylphosphine is a bulky and electron-rich phosphine ligand that is highly effective for palladium catalyzed cross-coupling reactions such as Heck and Suzuki coupling, Buchwald-Hartwig amination of aryl chlorides, and α-arylation reactions of ketones.

Other applications:
  • palladium-catalyzed carbonylation of aryl and heteroaryl halides
  • palladium-catalyzed synthesis of (hetero)aromatic nitriles
  • palladium-catalyzed aminocarbonylation of aryl halides

Features and Benefits

  • Mild reaction condition
  • Low catalyst loading
  • High yield and turn over number

General description

Sold in collaboration with Solvias AG

cataCXium® A is commonly used as a catalyst in cross-coupling reactions, such as Suzuki and Sonogashira reactions.
