4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos) is a wide-bite-angle (ca. 111°) bidentate diphosphine ligand with a rigid xanthene backbone. It plays a critical role in organometallic chemistry and industrial fine chemical synthesis, widely used in combination with palladium, ruthenium, and rhodium catalysts. Xantphos is highly effective for Buchwald-Hartwig amination reactions forming C-N bonds, Suzuki-Miyaura cross-coupling, and selective hydroformylation of olefins to generate linear aldehydes. Its unique steric and electronic properties make it an indispensable catalytic ligand for the synthesis of complex pharmaceutical intermediates, agrochemicals, and organic electronics globally.

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.
