Overview

Xantphos is a bidentate ligand that is employed in various metal-catalyzed reactions, including cross-couplings, Buchwald-Hartwig cross-coupling reactions, C-X bond formation, hydroformylation, Miyaura borylation reaction, Stille coupling, Suzuki-Miyaura coupling, (hetero)arylation, amination, and amidation.
Application
Ligand used in a synthesis of heterocycles by palladium-catalyzed C-N cross coupling of 3-bromothiophenes with 2-aminopyridines. Also used in a ruthenium-catalyzed alkylation of active methylene compounds with alcohols. 
Metal chelating ligand for catalysis.
