(E,E,E,E,E,E)-Hexakis(2-phenylethenyl)benzene (7a) and some derivatives 7b-e with three or nine alkoxy groups were prepared by a synthetic sequence of four steps. Starting from 1,3,5-tribromo-2,4,6-trimethylbenzene (1) the first three styryl groups were introduced by a Heck reaction, and the second three styryl groups by a Wittig-Horner reaction.
(E,E,E,E,E,E,E)-六(2-苯基乙烯基)苯 (7a) 和一些带有三个或九个烷氧基的衍生物 7b-e 是通过四个步骤的合成顺序制备的。从 1,3,5-三溴-2,4,6-三甲基苯 (1) 开始,通过 Heck 反应引入前三个苯乙烯基团,通过 Wittig-Horner 反应引入后三个苯乙烯基团。
