A local proton source in a [Mn(bpy-R)(CO) 3 Br]-type redox catalyst enables CO 2 reduction even in the absence of Brønsted acids

The effect of a local proton source on the activity of a bromotricarbonyl Mn redox catalyst for CO 2 reduction has been investigated. The electrochemical behaviour of the novel complex [ fac -Mn(dhbpy)(CO) 3 Br] (dhbpy = 4-phenyl-6-(1,3-dihydroxybenzen-2-yl) 2,2′-bipyridine), containing two acidic O...

Description
Summary:The effect of a local proton source on the activity of a bromotricarbonyl Mn redox catalyst for CO 2 reduction has been investigated. The electrochemical behaviour of the novel complex [ fac -Mn(dhbpy)(CO) 3 Br] (dhbpy = 4-phenyl-6-(1,3-dihydroxybenzen-2-yl) 2,2′-bipyridine), containing two acidic OH groups in the proximity of the metal centre, under a CO 2 atmosphere showed a sustained catalysis in homogeneous solution even in the absence of Brønsted acids.
