Carbanions containing leaving groups react in the presence of base with electrophilic alkenes giving products in which vinylic hydrogen is replaced with the carbanion moiety. They are formed via addition - β-elimination pathway analogous to the vicarious nucleophilic substitution in nitroarenes. In some cases, however, the cyclization - ring opening process takes place instead.
含有离去基团的碳负离子在碱的存在下与亲电子烯烃反应,生成产物,其中乙烯基氢被碳负离子部分取代。它们是通过加成-消除途径形成的,类似于硝基芳烃中的替代性亲核取代反应。但是,在某些情况下,会发生环化-开环过程。
