Abstract: Novel benzthiazole-N-oxides are obtainable by the reaction of halogenonitrobenzenes additionally activated by one or more electronegative substituents with mercaptomethyl compounds in an inert solvant in the presence of a base in the temperature range of from 20* to 160* C. The new benzthiazole-N-oxides are suitable for use as colored pigments e.g. for dyeing plastics.
