Fluorination of Nitro Compounds with Acetyl Hypofluorite
摘要:
Various types of nitro derivatives are fluorinated to form the CFNO2 moiety in very good yields using acetyl hypofluorite (AcOF). The corresponding nitro anion, preferably prepared with NaOMe, is added quickly to a cold (-75 degrees C) CFCl3 solution of AcOF, and although it contains water and acetic acid little or no protonation occurs because these proton donors are frozen. Many of the starting nitro derivatives were prepared by oxidizing the corresponding amino derivatives using the complex HOF.CH3CN, prepared by bubbling F-2 through aqueous acetonitrile.
