Efficient Amination of Activated and Non-Activated C(sp³ )-H Bonds with a Simple Iron-Phenanthroline Catalyst.

ABSTRACT: A readily 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 can be performed under open flask conditions.
