azabicyclic cyclopropanes (with Co catalyst). The rhodium-catalyzed 2H-pyrrole formation involving hydrogen shift is supported by deuterium-labeling experiments. The control experiments in the cobalt-catalyzed reaction indicate that the bicyclic aziridines as the primary product undergo a skeletal rearrangement assisted by metal iodide salts.
我们报告了通过使用铑和钴催化剂提供2 H-吡咯(含Rh催化剂)和氮杂双环环丙烷(含Co催化剂)对烯烃系异恶唑5(4 H)-ones进行的不同催化转化。氘标记实验支持了涉及氢转移的铑催化的2 H-吡咯的形成。钴催化反应中的对照实验表明,作为主要产物的双环氮丙啶类化合物在金属碘化物盐的辅助下进行了骨架重排。
