available catalyst consisting of iron dichloride in combination with 1,10‐phenanthroline catalyzes the ring‐closing C−H amination of N‐benzoyloxyurea to form imidazolidin‐2‐ones in high yields. The C−H amination reaction is very general and applicable to benzylic, allylic, propargylic, and completely non‐activated aliphatic C(sp3)−H bonds, and it also works for C(sp2)−H bonds. The surprisingly simple method
由二氯化铁与 1,10-菲咯啉组合组成的现成催化剂可催化N-苯甲酰氧基脲的闭环 C-H 胺化,以高产率形成咪唑烷-2-酮。C−H 胺化反应非常普遍,适用于苯甲基、烯丙基、炔丙基和完全非活化的脂肪族 C(sp 3 )−H 键,并且也适用于 C(sp 2 )−H 键。这种令人惊讶的简单方法可以在敞口烧瓶条件下进行。
