Proton reduction reaction catalyzed by homoleptic nickel bis-1,2-dithiolate complexes: Experimental and theoretical mechanistic investigations.

ABSTRACT: A series of homoleptic monoanionic nickel dithiolene complexes [Ni(bdt)₂](NBu₄), [Ni(tdt)₂](NBu₄), and [Ni(mnt)₂](NBu₄) containing the ligands benzene-1,2-dithiolate (bdt^2-), toluene-3,4-dithiolate (tdt^2-) and maleonitriledithiolate (mnt^2-), respectively, have been employed as electrocatalysts in the hydrogen evolution reaction with trifluoroacetic acid as proton source in acetonitrile. All complexes were active catalysts with TONs reaching 113, 158 and 6 for [Ni(bdt)₂](NBu₄), [Ni(tdt)₂](NBu₄), and [Ni(mnt)₂](NBu₄), respectively. Faradaic yield for hydrogen evolution reaction reaches 88 % for 2^- , which also d
