Descrição: A unified strategy for nickel(0)‐catalyzed C−H allylations, alkenylations, and dienylations has been realized through versatile hydroarylations of allenes with ample scope. Thus, an inexpensive nickel catalyst modified with a N‐heterocyclic carbene ligand enabled the direct transformation of C−H bonds of biologically relevant imidazole and purine derivatives with full control of regio‐ and chemoselectivity. Einfache C‐H‐Aktivierung: Gegabelte Nickel(0)‐katalysierte C‐H‐Allylierungen, Alkenylierungen und Dienylierungen wurden durch Hydroarylierung von Allenen unter vollständiger Kontrolle der Regio‐ und Chemoselektivität durchgeführt. Das Substratspektrum umfasst eine Vielzahl von Imidazol‐ und Purinderivaten.
