C5H5FeC6H7 (1) reacts with HBF4-Et2O to give the tetrafluoroborato complex C5H5Fe(C6H8)FBF3 (2).The BF4 coordination in solution is demonstrated by 19F-DNMR experiments.The ligands BF4(-) and C6H8 in 2 are substituted stepwise by the dimethyl chalcogen compounds EMe2 (E = S, Se, Te; Me = CH3).The elimination of undecomposed C6H8 demonstrates the ability of this reaction for the synthesis of 1,3-cyclohexadienes.The isolable cation (+) (5a) serves as a useful tool for the preparation of carbonyl free (cyclopentadienyl)iron compounds.
