Potassium Hydroxide → 2,2'-(1,3-Phenylene)bis[1,10-phenanthroline]

Participants

Reaction Steps

101 g of 8-amino-7-quinoline carboaldehyde was reacted with 45 g of 1,3-diacetylbenzene and 100 g of 85% potassium hydroxide in 1800 ml of ethanol for 10 hours while refluxing and a reactant was treated by a normal method to obtain 100 g of 1,3-di(1,10-phenanthroline-2-yl)benzene. 40.8 g of this 1,3-di(1,10-phenanthroline-2-yl)benzene was reacted with 400 ml of phenyl lithium (0.94 M cyclohexane-ether solution) in 750 ml of toluene for 2.5 hours while cooling with ice and a reactant was treated by a normal method. The obtained product was reacted with 118 g of nitrobenzene at 110° C. for 3 hours and a reactant was treated by a normal method to obtain 22.8 g of E-20.
