Figure 1: The left panel shows the nitrogen-activating tungsten complex of Schneider and co-workers.  The middle panel illustrates its electronic structure with a molecular orbital scheme and exemplary electronic excitations. We identified the following possible photochemical processes as shown in the right panel: a direct dissociation (red arrow) and a quasi-thermal N-N photodissociation (black/blue arrows; adapted from JACS Au 2021, 1, 6, 879–894).
