N2 - Metal-ligand cooperation (MLC) plays an important role in bond activation processes, enabling many chemical and biological catalytic reactions. A recent new mode of activation of chemical bonds involves ligand aromatization-dearomatization processes in pyridine-based pincer complexes in which chemical bonds are broken reversibly across the metal centre and the pincer-ligand arm, leading to new bondmaking and -breaking processes, and new catalysis. In this short review, such processes are briefly exemplified in the activation of C-H, H-H, O-H, N-H and B-H bonds, and mechanistic insight is provided. This new bond activation mode has led to the development of various catalytic reactions, mainly based on alcohols and amines, and to a stepwise approach to thermal H2 and light-induced O2 liberation from water.
