Trogers bases (TBs) react with dimethyldioxirane to produce the corresponding N-oxides in excellent yields. Upon treatment with acetic anhydride, these N-oxides undergo a Polonovski-type reaction that involves fragmentation and ultimate nitrogen–nitrogen bond formation to form hydrazines. Steric effects are evident in both the oxidation step and in the step involving the activation of the N-oxide, such
Trogers 碱 (TBs) 与二甲基二环氧乙烷反应以极好的收率生成相应的 N-氧化物。用乙酸酐处理后,这些 N-氧化物会发生 Polonovski 型反应,该反应涉及断裂并最终形成氮 - 氮键以形成肼。在氧化步骤和涉及激活 N 氧化物的步骤中,空间效应都很明显,因此某些 TB 不适用于该过程。
