Using sulfinamides as a new reagent for preparation of asymmetrical thioethers has been developed under metal-free conditions. The reactions proceeded smoothly without the use of stinky thiophenol, highly toxic sulfonyl chloride or oxidant. Such a simple, efficient transformation provides an attractive approach to various diaryl sulfides in good to excellent yields.
在不含金属的条件下,已开发出使用亚磺酰胺作为制备不对称硫醚的新试剂。反应平稳进行,无需使用臭味的苯硫酚,剧毒的磺酰氯或氧化剂。这种简单,有效的转化为各种二芳基硫醚提供了一种诱人的方法,收率好至极好。
