Cover Feature: Electrocatalytic Proton Reduction by a Cobalt Complex Containing a Proton‐Responsive Bis(alkylimdazole)methane Ligand: Involvement of a C−H Bond in H 2 Formation (Chem. Eur. J. 55/2020)

Abstract

The design of proton‐responsive ligands and their use in the field of homogeneous electrocatalytic proton reduction is reported in this work. The cobalt complex, [Co(HBMIMPh2)2]2+ comprises two bis(1‐methyl‐4,5‐diphenyl‐1H‐imidazol‐2‐yl)methane (HBMIMPh2) ligands that contain an acidic methylene moiety in their backbone. The reported results represent the joint involvement of a base metal‐hydride and a C−H bond in electrocatalytic proton reduction and are of interest to the development of responsive ligands for molecular (base)metal (electro)catalysis.
