A method for the reduction of a manganese nitride to ammonia is reported, where light-driven proton-coupled electron transfer enables the formation of weak N-H bonds. Photoreduction of (saltBu)MnVN to ammonia and a Mn(II) complex has been accomplished using 9,10-dihydroacridine and a combination of an appropriately matched photoredox catalyst and weak Brønsted acid. Acid-reductant pairs with effective bond dissociation free energies between 35–46 kcal/mol exhibited high efficiencies. As a result, this light-driven method may provide a blueprint for new approaches to catalytic homogenous ammonia synthesis under ambient conditions.
