An electrochemical dehydrogenative amination for the synthesis of benzimidazoles was developed. This electrosynthesis method could address the limitations of the C(sp3)–H intramolecular amination synthesis reaction and provide novel access to obtain 1,2-disubstituted benzimidazoles without transition metals and oxidants. Under undivided electrolytic conditions, various benzimidazole derivatives could
开发了用于合成苯并咪唑的电化学脱氢胺化反应。这种电合成方法可以解决 C(sp3)-H 分子内胺化合成反应的局限性,并为在没有过渡金属和氧化剂的情况下获得 1,2-二取代苯并咪唑提供新途径。在未分割的电解条件下,可以合成各种苯并咪唑衍生物,表现出官能团耐受性。
