Doering-Hoffmann or the phenyl(trihalomethyl)mercurial procedures from allylic and vinylic compounds of these elements. The reaction of vinyltrimethyltin with phenyl(bromodichloromethyl)mercury (to give 2,2-dichlorocyclopropyltrimethyltin) was complicated by a side reaction in which the phenylmercuric bromide formed cleaved the vinyl group from tin. The H2PtCl6-catalyzed addition trichlorosilane to 1,1-dichloro-2-vinylcyclopropane
通过Doering-Hoffmann或苯基(三卤甲基)汞的方法,由这些元素的烯丙基和乙烯基化合物制备了十七种新的碳,硅,锗和锡的宝石-二卤代环丙基取代的衍生物。乙烯基三甲基锡与苯基(溴二氯甲基)汞的反应(得到2,2-二氯环丙基三甲基锡)由于副反应而复杂化,在副反应中,形成的苯基溴化汞将乙烯基从锡上裂解。H 2 PtCl 6催化将三氯硅烷加成到1,1-二氯-2-乙烯基环丙烷中得到预期的1,1-二氯-2-(β-三氯甲硅烷基乙基)环丙烷,但是氢化三甲基锡向该烯烃的热加成显然是通过自由基链机理进行的,从而得到开环产品。我3 SNCH 2 CHCHCH 2 -CCl 2 H.
