Abstract

A new method for copper-catalyzed P-C bond formation through reaction of phosphorus nucleophiles with diaryliodonium salts at room temperature is described. Most target products are obtained with this method in high yields within a short reaction time of 10 min. It can be easily adapted to large-scale preparations. When unsymmetrical iodonium salts are employed, nucleophilic substitution occurs preferentially on the sterically hindered aromatic ring or the more electron-deficient ring.
