MnCl2‐Catalyzed C−H Alkylations with Alkyl Halides

C−H alkylations with challenging β‐hydrogen‐containing alkyl halides were accomplished with sustainable MnCl2 as the catalyst under phosphine‐ligand‐free conditions. The proximity‐induced benzamide C−H activation occurred with ample substrate scope through rate‐determining C−H metalation, also setting the stage for manganese‐catalyzed oxidative C−H methylations.
