A Ni-catalyzed direct C-H alkylation ofN-quinolylbenzamides using alkylsilyl peroxides as alkyl-radical precursors is described. The reaction forms a new C(sp3)-C(sp2) bondviathe selective cleavage of both C(sp3)-C(sp3) and C(sp2)-H bonds. This transformation shows a high functional-group tolerance and, due to the structural diversity of alkylsilyl peroxides, a wide range of alkyl chains including functional groups and complex structures can be introduced at theortho-position of readily availableN-quinolylbenzamide derivatives. Mechanistic studies suggest that the reaction involves a radical mechanism.

Triazole assistance enabled the first iron-catalyzed C?H alkynylation of arenes, heteroarenes, and alkenes. The modular TAM directing group set the stage for a sequential C?H alkynylation/annulation strategy with ample scope, enabling the iron-catalyzed assembly of isoquinolones, pyridones, pyrrolones, and isoindolinones with high levels of chemo-, site-, and regioselectivity.

Nickel-catalyzed direct alkynylation of C(sp2)-H bonds of amides using commercially available, inexpensive 8-aminoquinoline as a removable bidentate directing group is described. The present ortho-alkynylation has a broad substrate scope, funct
