CO2 activation by manganese pincer complexes through different modes of metal–ligand cooperation

Abstract

We report here the activation of CO₂ using two Mn-PNN pincer complexes that can exhibit different modes of metal–ligand cooperation amido/amino mode that involves [1,2]-activation of CO₂ and dearomatization/aromatization mode that involves [1,3]-activation of CO₂. We also compare their catalytic activity for CO₂ hydrogenation.
