Inside Cover: Electrocatalytic Hydrogen Production by a Nickel(II) Complex with a Phosphinopyridyl Ligand (Angew. Chem. Int. Ed. 17/2016)

Electrocatalytic H 2 production by a molecular catalyst containing an inexpensive metal can contribute to the resolution of environmental problems. In their Communication on page 5247 ff., H. Masuda et al. describe the synthesis of a novel Ni II complex, containing a bidentate phosphinopyridyl ligand with an amine base as a proton‐transfer site, as a H 2 production catalyst. Electrochemical measurements with the complex show a higher rate of H 2 production under weak‐acid conditions using acetic acid as the proton source.
