Cross-coupling between diphenylphosphine oxide and halogenated benzoic acids catalyzed by Pd/C in water is a green, simple and fast protocol to obtain water-soluble tertiary phosphine oxides without the addition of ligands and additives. Low reaction times, microwave irradiation, and high substrate scope make this method general and excellent for lab- and large-scale synthesis without the need to use organic solvents for neither reaction nor workup.
