A novel and efficient method for selective synthesis of diaryl sulfoxides and m-arylthio sulfones has been achieved from readily available arylsulfinic acids and arenes via an unusual sulfinyl cation, providing a range of structurally diverse products in good to excellent yields under mild conditions. Notably, mechanistic investigations suggested m-arylthio sulfones were generated from diaryl sulfoxides
用于二芳基亚砜和选择性合成了一种新的且有效的方法米芳硫基砜已经从容易获得的芳基亚磺酸和芳烃经由一个不寻常的亚磺酰基阳离子实现,提供一系列的结构上不同的产品以优良至在温和的条件下具有优异的产率。值得注意的是,机械的调查建议米从碳酸二芳基亚砜和亚磺酰阳离子通过氧化还原反应和亲电芳香取代处理的顺序生成的芳硫基砜。
