An unusual, stepwise, two-carbon fragmentation-based mechanistic pathway through domino amidation–aziridination–decarbonylation–I2-mediated aminative cyclization–oxidation has been unravelled for the reaction between α,α-diiodo-α’-acetoxyketones and o-phenylenediamine in the absence of any added reagents such as acids, catalysts or bases as oxidants.
α,α-二碘-α'-乙酰氧基酮和邻苯二胺之间的反应通过多米诺酰胺化-氮丙啶化-脱羰-I 2介导的氨基环化-氧化的不寻常的、逐步的、基于双碳碎片的机制途径已被揭开。在没有任何添加试剂如酸、催化剂或碱作为氧化剂的情况下。
