A direct decarbonylative phosphorylation of benzoic acidscatalyzed by palladium was disclosed. Under the reaction conditions, a wide range of carboxylic acids coupled readily with all the three kinds of P(O)–H compounds, i.e. secondary phosphine oxides, H‐phosphinates and H‐phosphonates, producing the corresponding organophosphorus compounds in good to high yields. This reaction could be conducted

developed for photocatalytic P(O)–C(sp2) coupling of (hetero)aryl halides with H-phosphine oxides or H-phosphites under the irradiation of visible light or sunlight. The thioxanthen-9-one/nickel dual catalysis mediates this phosphonylation to give arylphosphine oxides and arylphosphonates in moderate to excellent yields. This transformation is widely tolerant to a range of functional groups and proceeds
