ranging from hydrogen evolution to C-H functionalization. However, the use of such complexes often requires polydentate, bulky ligands to stabilize the catalytically active Co(I) oxidation state from deleterious disproportionation reactions to enable the desired reactivity. Herein, we describe the use of bidentate electronically asymmetric ligands as an alternative approach to stabilizing transient Co(I)

Thermal energy harvesting using thermoelectrochemical cells (thermocells) is a sustainable method to produce electricity without carbon dioxide emissions. The solvent and redox couple used in the electrolyte play an important role in determining both the safety and performance of thermocells, and development of leak-free electrolytes with high performance is particularly important for transportable devices
A new method of single-stage synthesis of perfluoroalkylated arenes via cross-coupling of bromo (in some cases, chloro) arenes and heteroarenes (derivatives of benzene, pyridine and furan) and organic perfluoroalkyl halides involving complexes of nickel and cobalt in low oxidation state with α-diimines under mild conditions was proposed. Perfluoroalkylated products are obtained in good yields in the
