Phenanthrene derivatives play an important role in pharmaceutical chemistry and material science. Due to its advantages of green, mild reaction conditions and great application potential, visible light catalysis has become a powerful tool in organic synthesis. In this paper, under the catalysis of photocatalyst Ir[dF(CF3)ppy]2(dtbbpy)PF6, a series of 10-phenanthrenol derivatives were synthesized from 2-arylbenzoyl acetate derivatives in moderate to good yields through intramolecular cycloaromatization. In addition, the plausible reaction mechanism was also proposed.
Key words: visible-light photocatalysis, radical reaction, intramolecular cycloaromatization, phenanthrenols
