Article abstract of DOI:10.1246/cl.1990.963

Acridine Derivatives (9,10-dihydro-10-methylacridine and acriflavine) act as efficient and stable photocatalysts for reductive dechlorination of p-chlorobiphenyl as well as dehalogenation of bromochlorobenzenes with sodium borohydride in acetonitrile/H2O (9:1 v/v) at 298 K.In the case of acriflavine, the limiting quantum yield at irradiation wavelength λ = 350 nm has reached 0.63.
