experiment without Me3NFPY·OTf (Table 1, entries 13, 14),
our protocol should form a benzocyclic compound via a
cationic pathway. Furthermore, the high ligand dependency of
this reaction suggests that the cobalt complex could
significantly interfere in the transition state of the carbon−
carbon bond forming step. Both single-electron oxidation of the
carbon radical by the cationic cobalt species and intramolecular
nucleophilic trapping by the arene ring might occur
simultaneously in a concerted transition state.23 The origin of
the ligand effect of complex 8 is under investigation.
