Synthesis of 2,4-Diamino-6-arylpyridine-3,5-dicarbonitriles and Study of Their Optical Properties
摘要:
2,4-Diamino-6-arylpyridine-3,5-dicarbonitriles were synthesized by the nucleophilic substitution of bromine in 4-amino-2-bromo-6-arylpyridine-3,5-dicarbonitriles. The optical properties of the synthesized compounds were studied to show that they fluoresce in solution and in the solid state in the violet region of the spectrum.

Abstract 4-Amino-6-aryl-2-sulfanylpyridine-3,5-dicarbonitriles were obtained in two ways: by nucleophilic substitution of the halogen atom in 2-halopyridines under the action of thiols and by alkylation of pyridine-2-thiones with alkyl halides.
