Chemists from Freiburg have succeeded in converting polynuclear transition metal carbonyls into their homoleptic complex cations using typical inorganic oxidants. In their work, the research team of Malte Sellin, Christian Friedmann and Prof. Dr. Ingo Krossing from the Institute of Inorganic and Analytical Chemistry and Maximilian Mayländer and Sabine Richert from the Institute of Physical Chemistry at the University of Freiburg show that the anthracene derivative with a half-step potential of 1.42 Volts vs. Fc0/+ can be converted to the radical de-electronating salt by a nitrosonium salt.
