Not to be confused with Xantphos.

XPhos is an organophosphorus compound derived from biphenyl. Its palladium complexes exhibit high activity for Buchwald-Hartwig amination reactions involving aryl chlorides and aryl tosylates. Both palladium and copper complexes of the compound exhibit high activity for the coupling of aryl halides and aryl tosylates with various amides.[1] The ligand has convenient handling characteristics since it is air-stable.[2]
