The syntheses of the 7-chloro-, 4,7-dichloro-, 5- and 7-trifluoromethyl, 5-chloro-6-trifluoro-methyl- and 5-chloro-7-trifluoromethyl- derivatives of 3-amino-2,1-benzoisothiazole are described. Preparative details are included for a number of the precursors to the benzoisothiazole derivative which have not previously been described. Visible spectra of some azo dyes prepared from the title compounds
