  Sequential Friedel-Crafts Diacetylation of Ferrocene: Interannular Proton Transfers as a Mechanistic Probe

  摘要：

  (Pentadeuteriocyclopentadienyl)cyclopentadienyliron(II), 4, was prepared by the sequential addition of lithium tris(trimethylsilyl)cyclopentadienide and lithium pentadeuteriocyclopentadienide to FeBr2 followed by fluoride-induced removal of the trimethylsilyl groups of the resulting ferrocene 3. Analysis of the deuterium content of the acetylferrocene 5 and the 1,1'-diacetylferrocene 7, obtained from the Friedel-Crafts acetylation of 4, reveals that the former is formed by initial exo attack of AlCl3-CH3COCl, whereas precomplexation of the electrophile at the metal center (endo attack) precedes the formation of the latter.
