Title: Ligand Transformations and Efficient Proton/Water Reduction with Cobalt Catalysts Based on Pentadentate Pyridine‐Rich Environments (in German)

Journal Article · · Angewandte Chemie
; ; ; ; ; ; ;

Abstract A series of cobalt complexes with pentadentate pyridine‐rich ligands is studied. An initial Co II amine complex 1 is prone to aerial oxidation yielding a Co III imine complex 2 that is further converted into an amide complex 4 in presence of adventitious water. Introduction of an N‐methyl protecting group to the ligand inhibits this oxidation and gives rise to the Co II species 5 . Both the Co III 4 and Co II 5 show electrocatalytic H 2 generation in weakly acidic media as well as in water. Mechanisms of catalysis seem to involve the protonation of a Co II H species generated in situ.
