4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos) is an organophosphine compound derived from the xanthene heterocycle. Recognized as a crucial bidentate ligand, its unique steric hindrance and electron-rich properties make it an essential reagent in organometallic chemistry for the efficient construction of complex chemical bonds, especially in challenging C-N and C-O coupling reactions.

Used as a ligand in cross-coupling reactions such as Buchwald, Suzuki, Negishi, Stille, and Heck.
Used in Buchwald–Hartwig aromatic amination; used as a ligand in Pd-catalyzed C-N cross-coupling reactions for synthesizing heterocycles (e.g., 3-bromothiophene with 2-aminopyridine).

Used in Ruthenium-catalyzed alkylation reactions of activated methylene compounds with alcohols; commonly used in the hydroformylation of olefins; complexes with transition metals are used as catalysts for carbonylation reactions.

Due to its anthracene skeleton and good electronic conductivity, it can be used as a component in conductive materials such as organic electronic devices and solar cells.
