Aryl-substituted ketene imines (1a–1i) have been studied both in dichloromethane and acetonitrile by cyclic voltammetry. In addition to the multi-annulated heterocycles products of type 2–4 previously obtained by ketene imines 1a–1d, the anodic oxidation of ketene imines containing electron-withdrawing substituents and electron-donating substituents at the ortho position, affords also monocyclic dimers
已通过循环伏安法在二氯甲烷和乙腈中研究了芳基取代的乙烯酮亚胺(1a-1i)。除了先前由烯酮亚胺1a-1d获得的2-4型多环杂环产物外,在邻位含有吸电子取代基和供电子取代基的烯酮亚胺的阳极氧化还提供了单环二聚体类型5(从1e-1f)和类型6(从1h-1i)。讨论了电子和空间效应的结果。
