Frontispiece: Local Proton Source in Electrocatalytic CO2 Reduction with [Mn(bpy–R)(CO)3Br] Complexes

Mn(bpy)‐type complexes bearing local proton source catalyse the electrochemical reduction of CO2. Depending on the strength of the Brønsted acid added to the solution, CO or formate are produced. Spectroelectrochemical studies under Ar and CO2 atmospheres show fast solvolysis and the dimer formation is suppressed, providing an atypical reduction mechanism of MnI catalysts. Spectroscopic evidence of Mn hydride formation supports the existence of different electrocatalytic CO2 reduction pathways. For more information, see the Full Paper by R. Gobetto, C.
