A successful synthesis of α-fluoro-β-ketosulfides using an electrophilic fluorination method has been reported for the first time. The reaction proceeds via an electrophilic fluorination of α-sulfenyl-β-diketones followed by an unexpected tandem deacylation. The resulting products, α-fluoro-β-ketosulfides, are easily oxidized to the corresponding α-fluoro-β-ketosulfones, which can be used for further
首次报道了使用亲电氟化方法成功合成α-氟-β-酮硫醚。该反应通过α-亚磺酰基-β-二酮的亲电氟化反应进行,然后发生意外的串联脱酰反应。所得产物,α-氟-β-酮基硫醚,很容易被氧化成相应的α-氟-β-酮基砜,可用于进一步有用的烯化反应。
