Pd(<scp>ii</scp>)-Catalyzed arylation of unactivated methylene C(sp³)–H bonds with aryl halides using a removable auxiliary

Abstract

A Pd(II)-catalyzed arylation of methylene C(sp(3))-H bonds in aliphatic amides directed by our newly developed PIP directing group with aryl iodides/bromides has been achieved. Arylation occurs efficiently with a broad range of aryl halides and amides.
