A copper-catalyzed reaction of phosphorus nucleophiles with diaryliodonium salts at room temperature delivers products of a P-C bond formation in high yields within a short reaction time of 10 min. The method can be easily adapted to large-scale preparations. With unsymmetrical iodonium salts, nucleophilic substitution occurs preferentially on the sterically hindered aromatic ring or the more electron-deficient ring.
