Alkenylation of heteroarenes with alkynes has been achieved through ligand‐assisted heteroaryl C(sp2)−H bond activation by an in situ generated cationic RuII complex directed by the biorelevant heterocyclic scaffolds benzothiazole and benzoxazole, giving broad scope with respect to the heteroarenes (thiophene, furan, N‐methyl pyrrole, and 3‐indole) and the alkynes (diaryl, dialkyl, and aryl alkyl)
