1- and 2-Phenylbiphenylene have been made from 1- and 2-lithiobiphenylene, respectively, by treatment with cyclohexanone followed by dehydration and dehydrogenation. 2-Phenylbiphenylene has also been made by pyrolysis of 4- and 5-phenyl-biphenylene-2,2′-iodonium iodide with cuprous oxide.
通过用环己酮处理,然后进行脱水和脱氢,分别由1-和2-硫代联苯制备1-和2-苯基联苯。2-苯基联苯也可以通过将4-和5-苯基联苯-2,2'-碘化碘与氧化亚铜热解而制得。
