Conclusions
-
1.
Reactions involving the exchange of the CO groups in cyclopentadienyltricarbonylrhenium for σ and π donor ligands (PPh3, P(OPh)3, P(OEt)3, AsPh3, pyridine, urotropin, tolan) have been investigated,
-
2.
The protonation of complexes with the general formula CpEe(CO)2L has been studied in a medium of CF3COOH by IE spectroscopy, and it has been shown that the basicity of the Re atom in the complexes increases with enhancement of the donor properties of the ligand.
-
3.
The basic properties of the rhenium atom are stronger than those of the Mn atom in the analogous derivatives of cyclopentadienyltricarbonylmanganese.
