An effective visible-light mediated Ru-catalyzed protocol for accessing 6H-benzo[c]chromenes from benzyloxybenzenediazonium salt via a sequence of dediazoniation, intramolecular radical cyclization and aromaticzation has been developed. The protocol features mild conditions, simple operation and high efficiency, providing a new approach for synthesizing 6H-benzo[c]chromenes.
Key words: visible light photoredox catalysis, Ru-catalysis, radical cycloaddition, 6H-benzo[c]chromene
