i-Pr2NEt as the reducing agent, N-aryl α-azido tertiary amides were first converted to the corresponding aminyl radicals through reduction of the azido group; the aminyl radicals then underwent N-to-N aryl migration to give α-anilinyl-functionalized amides. α-Azido secondary amides, on the other hand, reacted with the solvent ethanol and i-Pr2NEt to afford the imidazolinone products.
本文报道了 α-叠氮酰胺的两种新的可见光促进自由基反应。通过以i- Pr 2 NEt为还原剂催化[Ir(ppy) 2 (dtbbpy)]PF 6,N-芳基α-叠氮叔酰胺首先通过叠氮基的还原转化为相应的胺基;然后氨基自由基经历 N 到 N 芳基迁移,得到 α-苯胺基官能化的酰胺。另一方面,α-叠氮仲酰胺与溶剂乙醇和i- Pr 2 NEt 反应得到咪唑啉酮产物。
