Photoinduced electron-transfer oxygenation of 9,lO-dihydroanthracene was carried out with 2,4,6triphenylpyrylium tetrafluoroborate (TPP) and 9,lO-dicyanoanthracene (DCA) as sensitizers. The time course of the oxygenation products was studied, and the results showed that anthrone was formed as a prim

✦ Synopsis
Reaction of (a) superoxide and (b) ozonate radical-ions with the title dichloride does not give the corresponding endo-peroxide and ozonide,respectively.
A variety of products formed by nucleophilic substitution and reductive dehalogenation were isolated.
