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.

, p. 3121 - 3129 (2007/10/02)
Cation exchange resin (SO3H) is a highly selective dealkylation reagent for mixed esters of phosphorus oxyacids bearing primary and secondary alkyl groups.The desired products which were produced by dealkylation of the secondary alkyl group were obtained in high yields under anhydrous and mild conditions.Keywords - dealkylation; cation exchange resin; carbonium ion; phosphorus oxyacid ester; trialkyl phosphate; dialkyl phenylphosphonate; p-toluenesulfonic acid
