USE OF ARYLAMINOANTHRAQUINONES AS AZO COMPONENTS

1-Phenylaminoanthraquinone enters into azo coupling with diazo compounds of the 2,4-dinitrobenzenediazonium type and, in the presence of an N-methyl group or of electron-donating substituents at position 3 of the phenyl group, with 4-nitrobenzenediazonium salts to form 1-(4-arylazophenyl)anthraquinones.Derivatives of 2-phenylamino- and 1-hydroxy-4-phenylaminoanthraquinones and also 1,5- and 1,8-bis(phenylamino)anthraquinones react similarly, whereas 1-amino-, 1-methylamino-, and 1-phenylamino-4-phenylaminoanthraquinones are only capable of azo coupling in the form of the 1-N-acyl derivatives.
