Mercuration with mercury(II) trifluoroacetate of (η6-aniline)- or (N,N-dimethylaniline)-(η5-cyclopentadienyl)iron(II)

The reaction of mercury(II) trifluoroacetate with the hexafluorophosphate of the eta(6)-aniline-eta(5)-cyclopentadienyliron(II) cation under reflux in dry ethanol gives rise to N-mono- and N,N-disubstituted mercury-containing salts of this cation. The same mercury-containing salts have been synthesized by the action of mercury(II) trifluoroacetate on the deprotonation product of the (eta(6)-aniline)(eta(5)-cyclopentadienyl)-iron(II) cation. Direct mercuration of the [eta(6)-(N,N-dimethylaniline)](eta(5)-cyclopentadienyl)iron(II) cation into the para position of the benzene ring of the arene ligand has been performed. The reactivity of the compounds obtained has been studied.
