The first example of phenanthroline‐ t BuONa promoted intramolecular C−H arylation of 1,5‐diaryl‐1,2,3‐triazoles without the involvement of transition metals has been developed. Various fused 1,5‐disubstituted‐1,2,3‐triazoles of triazolophenanthridines were prepared with excellent yields and high site‐selectivity via simple and efficient intramolecular cyclization by using the 1,10‐phenanthroline‐ t BuONa reaction system.
