    • The basis effects have been examined by using larger basis sets (SDD/6-311+G(d,p) or SDD/6-311++G(d,p)) for the single point calculations. With these two basis sets, the overall activation barriers of paths A and B are close to those with the smaller basis set (Lanl2dz/6-311+G(d,p)), and the arene activation-first mechanism (Path A) is found to be more feasible no matter which basis sets are used

    • To examine the solvent effect in calculation, solution-phase optimizations for selected species (involved in rate-determining steps) have been performed. The optimized structures calculated in the solution phase share great similarity with those calculated in the gas phase. What's more, in solution phase calculations, the overall activation barriers of Path A and B are 16.5 and 32.9 kcal mol-1, which are very similar to those of the gas phase calculations (17.1 and 31.4 kcal mol-1, accordingly).

    • We also examined other possible forms of CMD mechanism (such as: use of an external AcO- as base, or open coordination sites from the carbamate side with the coordination of nitrogen or oxygen of the directing group). However, such mechanistic possibilities were all found to be unfavorable due to the high energy demands. Please see ESI for more details In this study, the C-H activation transition states of the CMD mechanism and the σ-bond metathesis mechanism directly occurring on B-Int2 have been located. However, their relative free energies are higher than those of B-TScmd and B-TSsigma. Please see the ESI for more details
