Through the reaction of acenaphthene and nitrobenzene, pure biacenaphthenyls and 5-(N-phenyl) aminoacenaphthene were prepared by recrystallizing the reaction mixture obtained under the molar ratio of AlCl-3 to acenaphthene of 1.2 and 2.4, respectively.

• 由苊与PhNO2的反应,在控制AlCl3与苊的摩尔比为1·2和2·4左右时,重结晶反应产物可得到联苊和5-(N-苯基)氨基苊。
