Annelation reaction between pentafluoropyridine and diaminodihydro substituted pyridine derivatives gave dipyrido[1,2-b:3′,4′-e][1,2,4]triazine systems I (Ar = C6H5, 4-MeC6H4, 3-O2NC6H4, etc.) as major products arising from the initial nucleophilic substitution of more nucleophilic N-amino group of pyridone ring at 4-position of the pyridine ring followed by intramol. cyclization at 3-position of pyridine ring. Also, 4-aryl-1,2-dihydropyridine-3,5-dicarbonitrile derivatives II were obtained as side products. This study involved multiple reactions and reactants, such as 2,3,4,5,6-Perfluoropyridine (cas: 700-16-3HPLC of Formula: 700-16-3).
2,3,4,5,6-Perfluoropyridine (cas: 700-16-3) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJè·¯molé? in pyridine vs. 150 kJè·¯molé? in benzene). Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. HPLC of Formula: 700-16-3
