On the reaction mechanism of redox transmetallation of elemental Yb with Hg(C6F5)2 and subsequent reactivity of Yb(C6F5)2 with pyrazole: a DFT investigation.

چکیده
DFT investigations of the redox transmetallation reaction of the diorganomercurial (Hg(C6F5)2) with Yb metal, yielding Yb(C6F5)2, allowed us to define a very low energy reaction mechanism. This involves formation of a metal-metal bonded, formally Yb(I)-Hg(I), intermediate valence complex, (C6F5)Yb-Hg(C6F5). The subsequent reactivity of the divalent ytterbium complex with pyrazole was also computationally investigated, indicating that σ-bond metathesis occurs at divalent ytterbium.

The successive addition of KCN and Ph3CCl to B(C6F4-C6F5-2)3 (PBB) affords triphenylmethyl salts of the [NC-PBB]- anion. By contrast, the analogous reaction with sodium dicyanamide followed by treatment with Ph(3)CCl leads to the zwitterionic aminoborane H2NB(C12F9)2C12F8, via nucleophilic attack on an o-F atom, together with CPh3[F-PBB]. Whereas treatment of [NC-PBB]- with either PBB or B(C6F5...
