Reaction of Mercury(II) Trifluoroacetate with Deprotonated ( 6-Toluene)-, ( 6-Diphenylmethane)-, and ( 6-Triphenylmethane)( 5-cyclopentadienyl)iron(II) Complexes. Mercuration of Some Cationic (Arene)(cyclopentadienyl)iron(II) Complexes
摘要:
Treatment with mercury(II) trifluoroacetate of deprotonated (eta(6)-toluene)- and (eta(6)-diphenylmethane)(eta(5)-cyclopentadienyl)iron(II) complexes gave mono-, di-, and trisubstituted [from (eta(6)-toluene)(eta(5)-cyclopentadienyl)iron(II) cation] mercury-containing salts. The reaction of mercury(II) trifluoroacetate with deprotonated (eta(6)-triphenylmethane)(eta(5)-cyclopentadienyl)iron(II) afforded only the corresponding symmetric mercury derivative. The same product was obtained by direct mercuration with mercury(II) trifluoroacetate of (eta(6)-triphenylmethane)(eta(5)-cyclopentadienyl)iron(II) on heating the reactants in boiling unhydrous ethanol. Reactions of the resulting mercury-containing compounds with acids, symmetrizing bases, and acylating agents were studied.
