Substituted 5-arylazopyrimidines and 2-arylazopyrimidines have been synthesized and investigated as dichroic dyes with positive dichroism, for liquid crystals. A promising series of 2-aryl-5-arylazopyrimidine dyes has been found, and a method is proposed for their synthesis by condensation of 2-aryl-5-aminopyrimidines with nitrosobenzenes in a superbasic medium.
