Nitrobenzene → HCID 19708508, compound

Participants

Reaction Steps

13.4 g (0.048 mol) of 4,4'-ditertiarybutyl-N,N-diphenylamine, 7.7 g (0.019 mol) of 4,4'-diiodobiphenyl, 7.7 g (0.056 mol) of anhydrous potassium carbonate, 0.53 g (0.008 mol) of copper powder, and 5 ml of nitrobenzene were mixed. The reaction mixture was then allowed to undergo reaction at a temperature of 200° to 215° C. for 4 hours. The reaction product was then extracted with 100 ml of THF. The insoluble contents were removed by filtration. The filtrate was then concentrated to obtain a crystal. The crude crystal thus obtained was then purified by column chromatography (carrier: silica gel; elute: 1/2 mixture of toluene and n-hexane) to obtain 4.3 g (yield: 31.7%) of N,N,N',N'-tetrakis(p-tertiarybutylphenyl)benzidine. The melting point of the product was from 402.0° C. to 403.0° C.
