A novel strategy for C-P bond formation has been developed. The reaction employed aromatic carboxylic acids as the source of aromatic groups to couple with three types of P(O)-H(2) compounds without the need to isolate intermediates, thereby achieving a one-pot construction of carbon-phosphorus bonds. The protocol demonstrated excellent applicability and functional group tolerance, enabling the production of Ar-P(O)R2 and Ar2-PPh with moderate to excellent yields.
