  alkenes and 2-amino-substituted alkenes , with the latter being the favoured products. The reactions with bulky lithium diethylamide and lithium 2-methylpiperidinoamide gave exclusively 1-amino-substituted products . The effect of the increased bulk of N-nucleophiles is opposite to that observed for the reactions of alkenes with C-nucleophiles Increasing electronegativity of the phenyl ring substituents

  1-苯基五氟丙烯易于与二烷基酰胺锂反应，在大多数情况下可生成1-氨基取代的烯烃和2-氨基取代的烯烃的混合物，后者是较受欢迎的产物。与大体积的二乙酰胺锂和2-甲基哌啶子基锂的反应仅得到1-氨基取代的产物。N-亲核试剂增加的作用与烯烃与C-亲核试剂反应观察到的相反，烯烃中苯环取代基的电负性增加会改变酰胺化锂对C2碳原子的进攻的区域选择性。烯胺的E与Z异构体比率发现烯属胺的异构体的比例随时间变化，并且观察到动力学异构体E与热力学异构体Z的缓慢异构化，而烯胺的异构体的比例没有随时间变化。
