[structure: see text] Transmetalation of beta-tributyl(styryl)stannanes with n-BuLi gives the functional equivalents of the corresponding styryllithium intermediates. Reaction of the intermediates with chlorotrimethylsilane, iodomethane, or dimethyl sulfate gives the substituted styryl products in moderate to good yields. In all cases, the configuration about the double bond was retained in the products
[结构:见正文]用正丁基锂对β-三丁基(苯乙烯基)锡烷进行重金属化,得到相应的苯乙烯基锂中间体的功能当量。中间体与氯代三甲基硅烷,碘甲烷或硫酸二甲酯的反应以中等至良好的产率得到取代的苯乙烯基产物。在所有情况下,有关双键的构型均保留在产品中。
