The reaction of 1-(disubstituted amino)-2,3-diphenylcyclopropenium salt with phenyl- and alkylmagnesium halides afforded, regioselectively, 1-aminocyclopropenes in good yields. The reactions of these 1-aminocyclopropenes were studied under acidic and nonacidic conditions to yield regioselective ring-opening products (C2–C3 and C1–C3 bond fissions of the cyclopropene) associated with the carbenium ions and carbene intermediates, respectively.
1-(二取代氨基)-2,3-二苯基环丙烯鎓盐与苯基和烷基卤化镁反应,以良好的产率获得了具有区域选择性的 1-氨基环丙烯。在酸性和非酸性条件下研究了这些 1-氨基环丙烯的反应,分别得到了与硒离子和碳烯中间体相关的区域选择性开环产物(环丙烯的 C2-C3 和 C1-C3 键裂解)。
