Raab 's biochemically active species, derived from dithranol ( 1 ), is the anion 1a (Sect. A), which is a photosensitizer. Its sensitizing potency is quantitatively compared with that of rose bengal, tetraphenylporphyrine and other sensitizers (Sect. B). In Sect. C the mechanism of the conversion of 1a with 1 Δg 18 O 2 to chrysazin ( 2 ) is elucidated.
