A number of substituted 6,13-dihalogenotriphenodioxazines have been synthesised (a) by condensing halogeno-p-benzoquinones with arylamines followed by cyclisation of the resulting bisarylamino-quinones with benzoyl chloride in nitrobenzene and (b) by condensing halogeno-p-benzoquinones with o-aminophenols in the presence of anhydrous sodium acetate in an alcoholic medium. A few triphenodithiazines
已经合成了许多取代的6,13-二卤代三苯并二恶嗪(a)通过将卤代对苯甲醌与芳胺缩合,然后将生成的双芳基氨基苯醌与苯甲酰氯在硝基苯中环化,以及(b)通过将卤代对苯甲醌与苯甲酰氯缩合而合成。在无水乙酸钠存在下,在酒精介质中邻氨基苯酚。已经通过将邻氨基苯硫醇锌锌与卤代对苯醌醌缩合制备了一些三苯并二噻嗪。
