Article abstract of DOI:10.1246/bcsj.55.3351

Photosensitized oxygenation of 10-methyl-9(10H)-acridinethione, 9H-xanthene-9-thione, and 9H-thioxanthene-9-thione at -78 deg C gave the corresponding ketones, 10-methyl-9(10H)-acridinone, 9H-xanthen-9-one, and 9H-thioxanthen-9-one quantitatively in a 3-10 min-irradiation.Weak chemiluminescence was observed from the irradiated solution upon warming-up.
