实验过程

Into a 50 mL three-neck flask were put 1.1 g (2.2 mmol) of 9-(4′-bromobiphenyl-4-yl)-10-phenylanthracene, 0.93 g (2.2 mmol) of N,N′,N′-triphenylbenzidine (abbreviation: DPBA), and 1.0 g (10 mmol) of sodium tert-butoxide, and the atmosphere in the flask was replaced with nitrogen. Then, 15 mL of toluene and 0.10 mL of tri(tert-butyl)phosphine (10 wt % hexane solution) were added into this mixture. After this mixture was degassed under reduced pressure while being stirred, 58 mg (0.10 mmol) of bis(dibenzylideneacetone)palladium(0) was added thereto. Then, the mixture was stirred at 90° C. for 3 hours. After the stirring, about 20 mL of toluene was added into the mixture. The mixture was subjected to suction filtration to remove the solid, the obtained filtrate was subjected to suction filtration through Celite (produced by Wako Pure Chemical Industries, Ltd., Catalog No. 531-16855), alumina, and Florisil (produced by Wako Pure Chemical Industries, Ltd., Catalog No. 540-00135). A solid obtained by concentration of the filtrate was recrystallized with toluene/hexane to give 0.92 g of a light yellow solid, which was the object of the synthesis, in a yield of 50%.
