The direct ortho alkylation of 8‐aminoquinoline‐based aryl amides was achieved with primary alkyl bromides in high yields in the presence of an iron catalyst, 1,2‐bis(diphenylphosphino)ethane (dppe), and PhMgBr in 2‐MeTHF.

nickel catalysis commonly requires high reaction temperatures and strong bases, translating into limited substrate scope. Herein, nickel‐catalyzed C−H alkylations of unactivated 8‐aminoquinoline amides have been realized under exceedingly mild conditions, namely at room temperature, with a mild base and a user‐friendly electrochemical setup. This electrocatalyzed C−H alkylation displays high functional
The Nickel(II)-Catalyzed Direct Benzylation, Allylation, Alkylation, and Methylation of C–H Bonds in Aromatic Amides Containing an 8-Aminoquinoline Moiety as the Directing Group
Direct alkylation via the cleavage of the ortho C–H bonds by a nickel-catalyzed reaction of aromaticamides containing an 8-aminoquinoline moiety as the directing group with alkyl halides is report...
