Counterion Effects in [Ru(bpy)₃](X)₂-Photocatalyzed Energy Transfer Reactions.

ABSTRACT: Photocatalysis that uses the energy of light to promote chemical transformations by exploiting the reactivity of excited-state molecules is at the heart of a virtuous dynamic within the chemical community. Visible-light metal-based photosensitizers are most prominent in organic synthesis, thanks to their versatile ligand structure tunability allowing to adjust photocatalytic properties toward specific applications. Nevertheless, a large majority of these photocatalysts are cationic species whose counterion effects remain underestimated and overlooked. In this report, we show that modification of the X counterions constitutive of [Ru(bpy)₃](X)₂ photocatalysts modulates their catalytic activities in intermolecular [2 + 2] cycloaddition reactions operating through triple
