Conclusions
-
1.
Reaction of σ-ferrocenoylmethyl-(π)-cyclopentadienyl)dicarbonyliron with HBF4 and triethyloxonium fluoroborate gives carboxonium salts of the type [C5H5(CO)2FeCH2C(OR)C5H4FeC5H5]+BF −4 , where R=H and C2H5, and reaction with iodine in ether gives a ketone-group complex with iodine.
-
2.
The reactions of the ethoxycarbonium salt [C5H5(CO)2FeCH2C(OC2H5)C5H4FeC5H5]+BF −4 -with Nal, NaOCOCF3, and PPh3 proceed with cleavage of the Fe-Cσ bond, while its reaction with NaBH4 proceeds without cleavage of this bond, while its reaction with NaBH4 proceeds without cleavage of this bond but with formation of C5H5(CO)2FeCH2CH(OC2H5)C5H4FeC5H5.
