Fig. 4. Mechanistic insight.(A) Decrease of protodehalogenation observed with phthalimide caused by stabilization of the OAC. For the x-ray structure (50% probability
ellipsoids), hydrogens and tBu/CF3 disorder are omitted for clarity. (B) Slower quenching is tolerated because of the increased OAC concentration. (C) Increasing active
Ni on cycle by activation of low-valent Ni oligomers.
