Abstract

Anthraselenazole derivatives.--New products are obtained by condensing 1 : 9-anthraselenazole-2 carboxylic acid or chloride with aminoanthraquinones, or derivatives thereof, to give the acid amides. According to examples, 1 : 9-anthraselenazole-2-carboxylic acid chloride is condensed with 1-aminoanthraquinone, 2-aminoanthraquinone, 1 : 5-diaminoanthraquinone, 1 : 4-diaminoanthraquinone, mono-benzoyl-1 : 5-diaminoanthraquinone, 1-amino-6-chloroanthraquinone, 1-aminoanthraquinone-6-carboxylic acid, followed by conversion to the carboxylic chloride; the products dye cotton and artificial silk or are intermediates for dyestuffs. Specifications 219,830 and 326,487, [both in Class 2 (iii), Dyes &c.], are referred to.
