The decomposition of 1-lithio-2-bromotetrafluorobenzene in the prensence of an excess of 1,2-dibromotetrafluorobenzene gives mainly a mixture of 2,3,2′- and 2,6,2′-tribromoheptafluorobiphenyls; several other products were also identified. 2,2′-dibromooctafluorobiphenyl is formed in 88% yield when 1-lithio-2-bromothetrafluorobenzene is treated with an excess of titanium tetrachloride.
在过量的1,2-二溴四氟苯存在下1-硫代-2-溴四氟苯的分解主要得到2,3,2′-和2,6,2′-三溴七氟联苯的混合物。还确定了其他几种产品。当用过量的四氯化钛处理1-硫代-2-溴四氟代苯时,以88%的收率形成2,2'-二溴八氟联苯。
