Copper-Catalyzed Bromination of C(sp3 )-H Bonds Distal to Functional Groups.

Tao Liu1, Michael C Myers2, Jin-Quan Yu1.   

Abstract

Selective bromination of γ-methylene C(sp3 )-H bonds of aliphatic amides and δ-methylene C(sp3 )-H bonds of nosyl-protected alkyl amines are developed using NBS as the brominating reagent and catalytic amount of CuII /phenanthroline complexes as the catalyst. Aryl and benzylic C-H bonds at other locations remain intact during this directed radical abstraction reaction.
