Voltammetry and constant current electrolysis was used to study the oxidative fluorination of PhSCH2COOMe, PhSCH2CONH2, PhSCH2COOPh and PhCH2CN in solvent-free Et3N·3HF and Et3N·3HF dissolved in CH3CN, THF, DME and sulfolane. Sulfolane, DME and THF containing Et3N·3HF show much lower oxidation limits when compared to CH3CN/Et3N·3HF. These compounds undergo simultaneous oxidation along with background
用伏安法和恒流电解法研究了在无溶剂的Et 3 N·3HF和Et 3 N·3HF溶于CH 3 CN中的PhSCH 2 COOMe,PhSCH 2 CONH 2,PhSCH 2 COOPh和PhCH 2 CN的氧化
氟化, THF,
DME和
环丁砜。与CH 3 CN / Et 3 N·3HF相比,含Et 3 N·3HF的
环丁砜,
DME和THF的氧化极限低得多。这些化合物与背景氧化过程同时进行氧化。无溶剂Et 3N·3HF具有更大的阳极电位范围,可用于氧化有机化合物。PhSCH 2 COOMe和PhSCH 2 COOPh的选择性电
氟化没有显示出明显的溶剂作用。已发现,与CH 3 CN相比,THF和
