BORIC ACID-CATALYZED SYNTHESIS OF FUSED 1,2,4-TRIAZINE DERIVATIVES: A NEW CLASS OF RED FLUORESCENT ORGANIC COMPOUNDS

Ali Darehkordi, Vahid Salehi, Fariba Rahmani, Masoud Karimipour

Abstract

Pyrido[1,2-b][1,2,4]triazines have been synthesized in good to excellent yields by condensation reaction between 1,6-diamino-2-oxo-4phenyl-1,2-dihydropyridine-3,5-dicarbonitriles and arylglyoxals in the presence of boric acid. The synthesized compounds have considerable red light emission in 650 nm range.

Keywords

arylglyoxals; pyrido[1,2-b][1,2,4]triazin-6-ones; red fluorescent dyes.
