Possible pathways for photoreactions of complex 1 in PBS. Dashed arrows refer to reactions in presence of 1-methylimidazole, and curly brackets are used to denote transient intermediates. The photodecomposition pathways of 1 in acidic aqueous solution have been reported previously;[30] they involve not only photoreduction to PtII and O2 evolution, but N2 release via the formation of nitrene intermediates, in contrast to N3 release as detected in the present work.
