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

摘要

Two-electron redox processes occurring at the core of dinuclear metal complexes are important because of their implication in a number of chemical transformations ranging from the photocatalytic production of dihydrogen to the oxidative functionalization of C—H bonds. Two-electron redox processes are also well documented for binuclear gold complexes as well as for gold/rhodium, gpld/iridium and gold/platinum heterobimetallic complexes. One of the common features displayed by all of these complexes relates to their ability to sustain two-electron redox chemistry without decomposition of the bimetallic core. As part of our interest in fundamental aspects of main-group chemistry, we have recently questioned whether similar processes could also be observed at the bimetallic core of main-group/transition-metal complexes.
