The excited state of phthalimide anion adds to cyclic, acyclic and aryl-conjugated alkenes in an efficient and regioselective manner to form [2]benzazepine-1,5-diones, substituted at positions 3 and/or 4. The reaction is independent of the ionization potential of the alkene. This process contrasts with the related reactions of N-methylphthalimide or phthalimide, which are limited by the requirement
邻苯二甲酰亚胺阴离子的激发态以有效和区域选择性的方式与环状、无环和芳基共轭烯烃加成形成 [2] 苯并氮杂-1,5-二酮,在 3 位和/或 4 位被取代。该反应独立于烯烃的电离电位。该过程与 N-甲基邻苯二甲酰亚胺或邻苯二甲酰亚胺的相关反应形成对比,后者受限于参与方的要求。
