MSE PRO™ 4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos), 98% Purity

MSE PRO™ 4,5-Bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos) is a versatile organophosphorus compound derived from xanthene, commonly utilized as a bidentate ligand due to its exceptionally wide bite angle. The ligand is valuable in the hydroformylation of alkenes, among other applications such as the coupling of heteroarylamines and aryl halides, Pd-catalyzed carbonylation reaction of aryl bromides and amines, Pd/Cu-catalyzed direct arylation of heteroarenes.

MSE Supplies offers various catalysts and ligands of coupling reaction. Please contact us for customization or bulk orders.
