Abstract

Two formamidinate bridged dirhodium(II,II) complexes with chelating diimine ligands L, [Rh₂(μ-DTolF)₂(L)₂]²⁺, were shown to electrocatalytically reduce CO₂ in the presence of H₂O. Analysis of the reaction mixture and headspace following bulk electrolysis revealed H₂ and HCOOH as the major products. The variation in relative product formation is discussed.
