Two-Electron Redox Chemistry and Reversible Umpolung of a Gold-Antimony Bond

A two‐way street! The two‐electron oxidation of a novel binuclear stibine gold compound induces an umpolung of the SbAu dative bond which switches from Sb→Au in the reduced state to Sb←Au in the oxidized state (see scheme). This reversible process can be triggered by the addition/elimination of a h...

Summary:A two‐way street! The two‐electron oxidation of a novel binuclear stibine gold compound induces an umpolung of the SbAu dative bond which switches from Sb→Au in the reduced state to Sb←Au in the oxidized state (see scheme). This reversible process can be triggered by the addition/elimination of a halogen‐molecule equivalent.
