実験手順

4-bromo triphenylamine 7.6 g (23.45 mmol), aniline 21.85 g (0.235 mol), sodium tert-butoxide 6.76 g (70 mmol), Pd2(dba)3[(tris(dibenzilidene acetone)dipalladium(0))] 0.86 g (0.938 mmol) and tri(tert-butyl)phosphine 0.23 g (1.173 mmol) in 500 ml round bottom flask were dissolved with toluene 200 ml, and refluxed for 12 hours. After the reaction was terminated, the reaction solution was cooled to room temperature, and 200 ml of distilled water was added thereto to extract an organic layer. The organic layer was dried over MgSO4, concentrated, and purified by silica gel column chromatography. The eluate was concentrated and dried to give N,N,N′-triphenyl-p-phenylenediamine (6.71 g, 85%).
