Triphenylvinyl bromide (I) and diphenylvinyl iodide (XII) can be made to undergo replacement of the halogen atom by a phenyl group; n-BuLi (2·5 moles) is added to a mixture of the vinyl halide and o-bromofluorobenzene in ether at −78° followed by warming to −35°. The intermediate o-lithium derivative in the reaction of I could be converted to o-methyltetraphenylethylene (VI) by treatment with methyl
可以使三苯基乙烯基溴化物(I)和二苯基乙烯基碘化物(XII)经历卤原子被苯基取代;在-78°下将正丁基锂(2·5摩尔)添加到卤化乙烯和邻溴氟苯在乙醚中的混合物中,然后加热至-35°。中间Ó在I的反应-锂衍生物可以被转化为ö -methyltetraphenylethylene(VI)通过用甲基碘或治疗ö与二溴化乙烯-bromotetraphenylethylene(V)。I的对氯衍生物(顺式和反式IX)进行相同的反应,然后用二溴乙烷处理,得到1-(o-溴基苯基)-2,2-二苯基乙烯(X),在每种情况下均以不同的立体异构体为主。
