Fluorination of anionic ?-complexes by cesium fluoroxysulfate
摘要:
Anionic sigma-complexes and related structures react with cesium fluoroxysulfate to give predominantly the C-fluoro derivatives: fluoronitrocyclohexadienes or substituted fluoronitrobenzenes. Oxidation or degradation of a complex to form substituted nitrobenzenes is also possible. The balance between all these processes is determined by the structure of the original complex.
