constituents of nitrogen-containing heterocycles, widely exist in functional compounds. Herein, we report an anodic oxidative (4 + 2) cyclization between anilines and o-phenylenediamines for the uniform construction of phenazines in a simple undivided cell. Dual C–H amination followed by oxidation represents an outstanding step and atom efficiency. A sequence of phenazines is produced with excellent functional
