研究了由二苯亚砜和三氟甲磺酸形成的硫盐活化的苯酚衍生物的分子间联芳基偶联反应。该方法是一个快速的一锅反应，在偶联产物中没有留下任何硫部分的痕迹。三取代苯醚也以适中的产率得到偶联产物。
An intermolecular biaryl coupling reaction of phenol derivatives activated by a sulfonium salt formed from diphenyl sulfoxide and trifluoromethanesulfonic anhydride has been developed. The method is a rapid, one-pot reaction leaving no trace of the sulfonium moiety in the coupling products. Tri-substituted phenyl ethers also gave coupling products in moderate yields.
