Catalytic aromatization of 1,4-dihydropyridines by radical cation salt prompted aerobic oxidation

Aromatization of Hantzch 1,4-dihydropyridines was achieved under radical cation salt induced conditions, in which triarylamine radical cation acts as an efficient catalyst to prompt the aerobic oxidation of 1,4-DHPs in a catalytic way.

NaI readily mediated oxidative aromatization of hantzsch 1,4-dihydropyridines with hydrogen peroxide at room temperature: A green procedure

The oxidative conversion of 1,4-dihydropyridines to give the corresponding pyridine derivatives in excellent yields was easily effected using the catalytic amount of NaI in combination with H2O2 (30%) as a green external oxidant. The
