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.
