Reaction Steps

4,4′-Bipyridine (10 g, 0.065 moles) and chloro-2,4-dinitrobenzene (13 g, 0.065 moles) in ethanol (150 ml) in a 250 ml flask were refluxed for fifteen hours and allowed to cool. The ethanol was removed under vacuum and acetone (200 ml) was added and the mixture was stirred. The suspension was filtered and dried under vacuum to yield 1-(2,4-dinitrophenyl)-4,4′-bipyridinium chloride (17.5 g).
