Here we investigate the photophysics and photochemistry of Ni(II) aryl halide complexes common to cross-coupling and Ni/photoredox reactions. Computational and ultrafast spectroscopic studies reveal that these complexes feature long-lived <sup>3</sup>MLCT excited states, implicating Ni as an underexplored alternative to precious metal photocatalysts. Moreover, we show that <sup>3</sup>MLCT Ni(II) engages in bimolecular electron transfer with ground-state Ni(II), which enables access to Ni(III) i ...[more]
