PREPARATION OF NEW ORGANIC LUMINOPHORES BASED ON 3,5-DIACETYLPYRIDINES

Lhotak, Pavel,Kurfuerst, Antonin

, p. 1937 - 1946 (2007/10/02)

The reaction of acetylacetone or sodium salt of oxymethyleneacetone with corresponding aldehydes has been used to prepare 3,5-diacetyl-1,4-dihydropyridines III which have been oxidized to diacetylpyridines VII.These compounds have been transformed by an acid-catalyzed reaction with benzaldehyde into the chalcones VIII which have been utilized for the Kroehnke synthesis of luminophoric terpyridines I and II.
