A new procedure for the synthesis of known azo pyridone dyes is presented. A series of 5-(substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones were prepared from ethyl 3-oxo-2-(substituted phenylazo)butanoates and cyanoacetamide in acetone using potassium hydroxide as a catalyst by simple refluxing the reaction mixture. The structure of these dyes was confirmed by FT-IR, NMR and UV-Vis spectroscopy.
Novi postupak za sintezu poznatih azo-piridonskih boja je opisan u radu. Serija 5-(supstituisanih fenilazo)-6-hidroksi-4-metil-3-cijano-2-piridona je pripremljena iz etil-3-okso-2-(supstituisanih fenilazo)butanoata i cijanoacetamida u acetonu korišćenjem kalijum-hidroksida kao katalizatora uz zagrevanje.
