Here, a facile and
selective synthesis method for cationic
azatriphenylene
derivatives was established by electrochemical intramolecular cyclization,
where atom-economical C–H pyridination without a transition-metal
catalyst or an oxidant is a key step. The proposed protocol is a practical
strategy for the late-stage introduction of cationic nitrogen (N+) into π-electron systems and broadens
the scope of molecular design ofN+-doped
polycyclic aromatic hydrocarbons.
