Xantphos yog ib qho organophosphorus compound muab tau los ntawm heterocycle xanthene. Nws yog siv raws li bidentate ligand thiab tsis zoo rau muaj qhov tshwj xeeb tshaj yog lub kaum sab xis. Xws li cov ligands tseem ceeb nyob rau hauv hydroformylation ntawm alkenes. Cov lus piv txwv ntawm nws qhov dav tom lub kaum ntse ntse, nws ua rau ob qho tib si cis thiab hloov ntawm cov platinum (II) chloride Muaj feem xyuam bidentate ligand nrog ntau dua lub kaum sab xis yog spanphos.

Lub ligand tau npaj los ntawm ob chav kev coj ua ntawm 9,9-dimethylxanthene nrog sec-butyllithium ua raws li kev kho nrog chlorodiphenylphosphine.
