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
