Photochemical reaction of 2-naphthyl-1,2-benzisothiazol-3(2H)-ones in benzene under argon gives ring-expansion isomer, benzonaphthothiazepinone, probably via homolytic cleavage of the S-N bond and intramolecular recombination of the biradical, followed by the hydrogen shift to regeneration of an aromatic ring.
