    • For the purpose of comparison with the results presented in the main text, we computed the energies for SET, IAT, and oxidative addition (OA) complex formation in the reaction of 2-pyrrolidinone (pyrr) with 3,5- dimethyliodobenzene (ArI) catalyzed by CuI and N, N ′-dimethylcyclohexane- 1,2-diamine (diamine) [see (a) in the figure below; for further details, see refs 16 and 18 ]. As shown in (b) in the figure below, SET is isoenergetic with the formation of the OA intermediate (δ G = 41 kcal/mol). Significantly, IAT is more favorable than either SET or OA (δ G = 28 kcal/mol). This suggests that as a general trend, electron-rich β-diketones promote reactions via SET, while phenanthrolines, diamines, and other less electron-rich ligands promote reactions via IAT
