Benzophenothiazin-5-one reacts with alkoxides,thiols or thiolates to give 6-alkoxy- and 6-alkyl(aryl)thiobenzophenothiazin-5-ones, respectively.Benzannelation of phenothiazin-3-one in the quinoneimine fragment markedly hinders reactions with O- and S-nucleophiles with retention of the reaction center in the quinoneimine fragment of the molecule.
