An organometallic dithiolene complex exhibiting electrochemically initiated hydrogen generation

Abstract

We clarify the electrochemical behavior of an organometallic cobalt dithiolene complex (1-NH) with a secondary sulfonyl amide (–NHSO₂–) substituted Cp ligand involving proton dynamics. The reductions of 1-NH and its deprotonated derivative (1-N⁻) are centered on the CpCoS₂ moiety. The 2e⁻ reduction of 1-NH quantitatively gives 1-N⁻ with hydrogen generation.
