以2,2′-二硫代双芳基为原料，与ZnCl2分子内偶联，合成了苯并苯甲酸锌环戊二烯中间体。反应进行顺利，选择性地以中等到较高的产率得到所需的联苯。1998爱思唯尔科学有限公司版权所有。
Biphenylene and its derivatives were synthesized using the intramolecular coupling of benzoannelated zincacyclopentadiene intermediates prepared from 2,2'-dilithiobiaryls with ZnCl2. The reaction proceeded smoothly and selectively to give the desired biphenylenes in moderate to good yields. (C) 1998 Elsevier Science Ltd. All rights reserved.
