2-Diphenylphosphinobenzoic acid is an organophosphorus compound with the formula (C6H5)2PC6H4CO2H. It is a white solid that dissolves in polar organic solvents. The ligand is a component of catalysts used for the Shell higher olefin process.[1] It is prepared by the reaction of sodium diphenylphosphide with the sodium salt of 2-chlorobenzoic acid.[2]
