The disperse dyes of the type -s-triazine derivatives have been synthesized by condensation of bromamine acid with aniline, then desulphonation and cyclisation to obtained 8-aminoceramidone, followed by its cyanuration and condensation with various aryl urea.The dyeing properties of these dyes were studied on polyester fabrics.

1-Amino-4-arylaminoanthraquinones (II) have been prepared in high yields by reacting 1-amino-4-chloroanthraquinone (Ia, 1 mol) with arylamines (6 mol) and anhyd.AlCl3 (5 mol) in nitrobenzene at room temperature. 1-Amino-2-bromoanthraquinone, 2-amino-1-chloroanthraquinone, 1-benzamido-4-chloroanthraquinone and 1-amino-5-chloroanthraquinone fail to give arylaminated products. 1-Amino-2,4-dibromoanthraquinone (Ic) gives only 4-arylaminated compounds (IIq-s) whereas 1-amino-8-chloroanthraquinone (Ie) gives 2-arylaminated derivatives (III).A plausible mechanism for the reaction has been suggested.The arylaminated compounds have been applied on polyester as disperse dyes and their dyeing properties evaluated.
AMINATION OF ANTHRAISOXAZOL-6-ONES

, p. 704 - 707 (2007/10/02)
The behavior of 3,5-dihalo derivatives of anthraisoxazol-6-one with respect to primary and secondary amines was studied. 5-Chloroanthraisoxazol-6-one undergoes amination particularly readily.The products of the reaction of isoxazoles with amines are the corresponding amino derivatives.The amination of 5-chloroanthraisoxazol-6-one in refluxing dimethylformamide (DMF) is accompanied by reductive cleavage of the isoxazole ring and the formation of 1-amino-4-arylaminoanthraquinones.Amination in the 5 position with substitution of a hydride ion takes place primarily in the reaction of 3-chloroanthraisoxazol-6-one with benzylamine or cyclohexylamine, whereas the chlorine in the 3 position is replaced by the action of morpholine or piperidine on the same substrate.
