(A) Reductive elimination of 10 is induced with visible light and Ir(ppy)3 or with visible light alone. (B) The oxidation potentials of Ir(III)* (1*) and Ir(IV) indicate that SEToxidation is unfavorable, suggesting an alternate mechanism. (C) UV-visual absorption spectrum of a 5:1 mixture of 9:1 shows evidence of a ground-state association between the two. (D) Stern-Volmer quenching study shows evidence of both static and dynamic quenching. Me, methyl; Ac, acetyl; ppy, 2-phenylpyridine; SET, single electron transfer; RE, reductive elimination. ΔG°ET, ground-state Gibbs free energy of electron transfer.
