electron-withdrawing effect of perfluoroalkyl groups, solution-stable perfluoroalkanesulfenic acids were synthesized for the first time by Cope-type elimination of the corresponding imines; the acids were identified by 1H NMR, 19F NMR, and IR spectroscopy and mass spectrometry. Trapping reagents were utilized to capture the in situ generated sulfenic acids, which provided further experimental evidence for
利用全氟烷基的强吸电子作用,通过Cope型消去相应的亚胺,首次合成了溶液稳定的全氟烷烃亚磺酸;这些酸通过 1H NMR、19F NMR、IR 光谱和质谱进行鉴定。捕获试剂用于捕获原位生成的次磺酸,这为这些氟化次磺酸的形成提供了进一步的实验证据。
