Anodic fluorination of some electrophilic alkenes (conjugated with electron-withdrawn groups), ethyl cinnamates, RC6H4CHCHCO2Et (R = H, CH3, CH3O, F and CF3), cinnamonitrile, C6H4CHCHCN, phenyl stryryl ketone, and t-butyl styryl ketone using ammonium fluorides as the fluorine source and supporting electrolyte, in CH2Cl2 as electrolytic solvent yields the expected vicinal difluoro compounds, as mixture
某些亲电子烯烃(与吸电子基团共轭),肉桂酸乙酯,RC 6 H 4 CHCHCO 2 Et(R = H,CH 3,CH 3 O,F和CF 3),肉桂腈,C 6 H 4 CHCHCN的阳极氟化使用氟化铵作为氟源和支持电解质,在CH 2 Cl 2中作为电解质,使用苯基苯乙烯基酮和叔丁基苯乙烯基酮,可得到预期的邻位二氟化合物,为赤型和苏型异构体的混合物。苯基3,5-二-的阳极氟化叔丁基-4-羟基苯乙烯基酮产生两种单氟化合物。讨论了可能的反应机理。
