The combination of thioxanthen-9-one and a nickel catalyst mediates an efficient photocatalytic P(O)-C(sp2) coupling of (hetero)aryl halides with H-phosphine oxides or H-phosphites under the irradiation of visible light to provide arylphosphine oxides and arylphosphonates in good yields. This transformation tolerates a wide range of functional groups and proceeds efficiently on a gram scale.
