A series of cobalt complexes with pentadentate pyridine-rich ligands is studied. An initial CoII amine complex 1 is prone to aerial oxidation yielding a CoIII 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 CoII species 5. Both the CoIII 4 and CoII 5 show electrocatalytic H2 generation in weakly acidic media as well as in water. Mechanisms of catalysis seem to involve the protonation of a CoII-H species generated in situ.

Alkylation of α,ω-alkanediamines and their N,N-disubstituted derivatives with 2-(chloromethyl)pyridinium chloride in the presence of hexadecyltrimethylammonium chloride as a phase-transfer catalyst gave conveniently the corresponding N,N,N',N'-tetrakis(2-
