Influence of the Bis-Carbene Ligand on Manganese Catalysts for CO₂ Electroreduction.

ABSTRACT: First row transition metal complexes have attracted attention as abundant and affordable electrocatalysts for CO₂ reduction. Manganese complexes bearing bis-N-heterocyclic carbene ligands defining 6-membered ring metallacycles have proven to reduce CO₂ to CO selectively at very high rates. Herein, we report the synthesis of manganese carbonyl complexes supported by a rigid ortho-phenylene bridged bis-N-heterocyclic carbene ligand (ortho-phenylene-bis(N-methylimidazol-2-ylidene), Ph-bis-mim), which defines a 7-membered ring metallacycle. We performed a comparative study with the analogues complexes bearing an ethylene-bis(N-methylimidazol-2-ylidene) ligand (C₂H₄-bis-mim) and a methylene-bis(N-methylimidazol-2-ylidene) ligand (CH₂-bis-mi
