Investigation of the effect of an external heavy atom and of sensitization on the photorearrangement of 3-aryloxyanthra-6-isoxazolones to naphthophenoxazine-8,13-diones shows that it takes place from the triplet and singlet excited states of the initial compounds.The photolysis of 1-azido-2-aryloxyanthraquinones leads to the formation of anthraisoxazolones from the singlet excited state by a synchronous mechanism and phenoxazines from the triplet state of the azides.
