In a constant-potential electrolysis (CPE) for the synthesis of phenanthridinones, TBAI plays a dual role as both a redox catalyst and a supporting electrolyte. This metal and oxidant free reaction proceeds with 100% current efficiency via an intramolecular C-H activation under mild reaction conditions and with a short reaction time.
