the other based on Pd-catalyzedcoupling reactions of arylhydrazides and arylhalides, followed by oxidation, were investigated. The Pd-catalyzed route efficiently led to the target compounds, unsymmetrical tris(arylazo)benzenes. These triple switches were preliminarily characterized in terms of their isomerization behavior using UV-vis and 1H NMR spectroscopy. The efficient synthesis of this new class

The 3,5-bis(5-carboxy-6-azauracil-1-yl)aniline (7) and 1,3,5-tris(5-carboxy-6-azauracil-1-yl)benzene (10) were prepared from 3-amino-5-nitroacetanilide (1) via intermediates 2–6. A series of othersubstituted 6-azauracil derivatives 9, 11-14 were also prepared.
