Abstract In den letzten Jahren haben Organocuprate im Allgemeinen und der Komplex [Cu(CF 3 ) 4 ] im Besonderen wegen ihrer elektronischen Strukturen erhebliches Interesse auf sich gezogen. Obwohl der Reaktivität dieser Spezies in diesem Zusammenhang eine Schlüsselrolle zukommen dürfte, fand dieser Aspekt bisher nur wenig Beachtung. Wir untersuchen hier systematisch die Reihe der Tetraalkylcuprate [Me n Cu(CF 3 ) 4− n ] und ihre Gasphasenreaktivität, die sowohl konzertierte reduktive Eliminierungen als auch Radikalverluste umfasst. Mit Hilfe quantenchemischer Rechnungen charakterisieren wir die elektronischen Strukturen der Komplexe und zeigen, wie sie mit der Reaktivität zusammenhängen. Wir finden, dass alle Ionen [Me n Cu(CF 3 ) 4− n ] invertierte Ligandenfelder aufweisen und dass sich die unterschiedlichen Reaktivitäten der individuellen Komplexe aus dem Zusammenspiel verschiedener Effekte ergeben.
