Conclusions

  1. 1.

    GeCl2 · C4H8O2 reacts withπ- C5H5(CO)2FeCl with the formation ofπ-C5H5(CO)2FeGeCl3 (I). Formation of complex (I) can be regarded as a result of insertion of GeCl2 into the Fe-Cl bond.

     
  2. 2.

    It was shown by NMR that in the complexesπ-C6H5(CO)2FeGeX3 (X=CI, I) the halogen atoms are very labile in tetrahydrofuran and enter into a disproportionation reaction.

     
  3. 3.
    Reaction of GeCl2·C4H8O2 withπ-C5H5(CO)2FeI yielded four complexes:π-C5H5(CO)2FeGeCl3,π-C5H5(CO)2FeGeCl2I,π-C5H5(CO)2FeGeClI2,π-C5H5(CO)2FeGeClI2, and π-C5H5(CO)2FeGeI3. Formation of four complexes most probably occurs as a result of the following: the product of GeCl2 insertion into the Fe-I bond,π-C5H5(CO)2 · FeGeCl2I, is unstable and disproportionates by the scheme
    $$5\pi - C_5 H_5 (CO)_2 FeGeCl_2 l \rightleftarrows 3\pi - C_5 H_5 (CO)_2 FeGeCl_3 + \pi - C_5 H_5 (CO)_2 FeGeClI|_2 + \pi - C_5 H_5 (CO)_2 FeGeI|_3 .$$
     
  4. 4.

    Four new complexes were obtained having the general formula:π-C5H5(CO)2FeGeX3 (X=F, Br, I, OCOCH3).
