Reaction Optimization^a

^aReactions were performed on 0.1 mmol scale. Yields were determined via ¹H NMR spectroscopic analysis of the crude reaction mixtures relative to 1,3,5-trimethoxybenzene as an internal standard.

^b2.5 equiv. alkene employed.

^cNo irradiation.

^d0 mol% 4-OMe-PhSH.

^ePhotocatalyst redox potentials were estimated relative to Fc⁺/Fc in MeCN (see Section S12).
