^aAll of the experiments were carried out in oxygen-free acetonitrile at 298 K with a photocatalyst concentration of 0.015 mM, with excitation at 330 nm. Data are reported with a ±95% confidence interval. In all cases, the quality of the fitting is assured by a R ² > 0.98.

^b k _q = K _SV/τ ₀, where τ ₀ is the unquenched excited-state lifetime of the photocatalyst.

^cThere is no evidence of there being correlation between the excited-state quenching of the photocatalyst and the increasing amounts of 3a up to a concentration of 4 mM.
