cf. CA 59:12787f. Bromination, iodination, nitration, and diazo-coupling of 5- and 7-amino-1,2,3-benzothiadiazoles, and some N-acyl derivatives, have been studied. The results largely confirm the interpretation of electrophilic substitution in the 1,2,3-benzothiadiazole system previously advanced. Some bromination reactions probably proceed by mechanisms other than simple electrophilic substitution. Spectroscopic anal. of the mixture of 5- and 7-nitro-1,2,3-benzothiadiazoles, obtained by nitration of the parent compound, shows that the 7-nitro isomer predominates. Preparation of nitro-, amino-, and hydroxy-1,2,3-benzothiadiazoles has been further investigated, particular attention being given to methods involving ring opening of appropriate benzothiazoles. The synthesis of 4-hydroxy-1,2,3-benzothiadiazole, an analog of 8-hydroxyquinoline, is described.
