facile and leads to the corresponding α‐fluoroketones under mild conditions and, as a result, this route is commonly employed for the synthesis of medicinally important compounds such as fluorinated steroids. However, despite the use of this methodology in synthesis, the mechanism of this reaction and the influence of structure on reactivity are unclear. A rigorous mechanistic study of the fluorination
烯醇酯与SelectFluor的反应很容易,并且在温和条件下会生成相应的α-氟代酮,因此,该路线通常用于合成重要的药用化合物,例如氟化类固醇。然而,尽管在合成中使用了该方法,但是该反应的机理和结构对反应性的影响尚不清楚。提出了对这些底物氟化的严格机理的研究,主要是通过详细而可靠的动力学实验得出的信息。这项研究的结果暗示了通过氧稳定的碳鎓物质进行的极性双电子过程,而不是涉及自由基中间体的单电子过程。
