i-C3H7SO2F and cyclo-C3H7C(O)F have been subjected to electrochemical fluorination in anhydrous hydrogenfluoride. The resulting products were fully analyzed by NMR spectroscopy. From the reaction balances, literature data and quantum chemical calculations, a new mechanism for carbon-chain isomerization during the electrochemical fluorination (ECF) is proposed. The key step in the formation of isomeric products
化合物i -C 4 H 9 SO 2 F,i -C 3 H 7 SO 2 F和环-C 3 H 7 C(O)F已在无水氟化氢中进行了电化学氟化。通过NMR光谱对所得产物进行全面分析。从反应平衡,文献数据和量子化学计算出发,提出了一种在电化学氟化过程中碳链异构化的新机理。据信形成异构体产物的关键步骤是涉及碳阳离子或双自由基中间体的闭环反应。

converting them into the corresponding sulfonyl chloride in the presence of MgCl2 (Figure 2B). Although great electrophiles, sulfonyl chlorides suffer from high instability and fast hydrolysis rates, which results in troublesome isolation procedures. Herein, we present a strategy which enables the conversion of aryland alkylsulfonamides into more robust, bench-stable sulfonyl fluorides in one operation. The
