Evidence of fluoride transfer from the anion of [Zr{C5H3[SiMe2(η1-NtBu)]2}]+[RB(C6F5)3]_ complexes to the zirconocenium cation
In summary, we have found experimental evidence to support a reaction pathway involving direct fluoride migration to the zirconium cation without previous transfer of C6F5. It is noteworthy that the opening of the silyl–amido bridge was not observed in the course of these activations. Experiments wi...

| Sumario: | In summary, we have found experimental evidence to support a reaction pathway involving direct fluoride migration to the zirconium cation without previous transfer of C6F5. It is noteworthy that the opening of the silyl–amido bridge was not observed in the course of these activations. Experiments with other donor ligands are in progress to investigate the conditions under which the ion pairs 1 and 2 may follow different decomposition routes and the possible mechanisms of these reactions. |
