Anodic fluorination of various nitrogen-containing heterocyclic propargyl sulfides using Et4NF·nHF (n=3,4) or Et3N·3HF as a supporting electrolyte and fluoride ion source in dimethoxyethane provided the corresponding monofluorinated products in moderate yields. Fluorination took place selectively at the position α to the sulfur atom of the sulfides and the heterocyclic moieties were not fluorinated
使用Et 4 NF· n HF(n = 3,4)或Et 3 N·3HF作为支持电解质和氟离子源在二甲氧基乙烷中对各种含氮杂环炔丙基硫化物进行阳极氟化,可提供中等产率的相应单氟化产物。在硫化物的硫原子的位置α处选择性地发生氟化,并且杂环部分完全不被氟化。
