Water → 1,1'-Oxybis(4-nitrobenzene)

Participants

Reaction Steps

1,4-Dinitrobenzene (3.52 g, 20.5 mmol), potassium carbonate (1.38 g, 10 mmol), and 4-chlorobenzoic acid (30 mg, 0.19 mmol) were heated in dimethylsulfoxide (8 mL) at about 100° C. for approximately 5.8 hours. The reaction was allowed to cool and was poured into water (20 mL). The reaction vessel was rinsed with an additional 10 mL of water and the rinses were combined. The combined aqueous suspensions were allowed to stand overnight. The solid was collected, washed with water, and dried to give 2.51 g (80% pure) of 4,4'-dinitrodiphenyl ether.
