Thioethers are converted to thiocyanates via fluorium-initiated dealkylative cyanation. Selectfluor is used as the oxidant, and trimethylsilyl cyanide is used as the cyanation reagent. The well-streamlined procedure is user-friendly, operationally simple, and step-economical. The current mechanistic studies show that the sulfur radical cation and cyano radical are both involved. They combine to deliver
硫醚通过氟引发的脱烷基氰化反应转化为硫氰酸酯。Selectfluor被用作氧化剂,三甲基甲硅烷基氰化物被用作氰化试剂。精简的过程是用户友好的,操作简单且经济的步骤。当前的机理研究表明,硫自由基阳离子和氰基自由基都涉及。它们结合在一起释放氰基ulf,这是脱烷基化后向硫氰酸酯的中间体。或者,亲核机理也是可能的。我们的脱脱烷基氰化在合成具有强亲电功能的硫氰酸酯方面也很有效。
