Oxidation führt zu Reduktion – redoxinduzierter Elektronentransfer (RIET)

Abstract: Elektronentransferreaktionen sind ein äußerst wichtiges Gebiet der Chemie, das bedeutende Auswirkungen auch für die Biologie, die Physik und die Materialwissenschaften hat. Die Vielfalt der Elektronentransferreaktionen ist so groß, dass Übersichtsartikel nicht genügen und es stattdessen Handbücher und Nachschlagewerke braucht.[1] Die Aufnahme eines Elektrons ist eine Reduktion und die Abgabe eines Elektrons eine Oxidation. Zur Erhaltung der Elektronen treten diese Vorgänge gekoppelt auf und werden als Reduktio… Show more

“…[3] Recently, we reported on the syntheses of a new strong molecular electron donor, namely, 1,2,4,5-tetrakis(tetramethylguanidino)benzene [ttmgb; see Equation (1)]. [4] Oxidation of ttmgb occurs slowly with O 2 from the air and spectroscopic data indicate two-electron oxidation.…”

“…In its oxidized form, the positive charges are delocalized, with two of the resonance structures being sketched in Scheme 1. In principle, ttmgb can be classified as a potentially non-innocent ligand (NIL) [11,12] that does not necessarily display a closedshell configuration. Thus, ligand-centered redox reactions might play a role in the case of the ttmgb ligand.…”

“…[2,3] Substituted p-quinones have been extensively used as ligands in coordination chemistry in recent years. [4][5][6] The remarkable properties that such ligands impart to their metal complexes make such compounds useful in a variety of fields, such as homogenous catalysis, [7] supramolecular chemistry, [5,8] coordination polymers, [9,10] and as bridging ligands in combination with redox active metal centers such as ruthenium. [11][12][13][14] The last field has gained tremendous attention in recent years because of ambiguities arising in oxidation-state formulations also with "organometallic-type" non-innocent ligands.…”
