Trinitiy of CO2 Activation


The Limberg group has shown in cooperation with the Kaupp group (TUB) that in bioinspired nickel-CO2 complexes the degree of CO2 activation depends on the nature of the alkali metal counterion, the strength of its interaction with the CO2 unit – and thus its special separation – as well as on further polar entities in the second coordination sphere. This is also reflected in the reactivity towards electrophiles which lead to C-O bond cleavage and CO formation.
