Photochemische Permutation von Indazolen zu Benzimidazolen
Hier stellen wir eine photochemische Strategie für die direkte Permutation von 1H‐ und 2H‐Indazolen zu Benzimidazolen vor. Dieser Ansatz beruht auf einem zweistufigen Mechanismus aus Tautomerisierung im angeregten Zustand und photochemischer Umlagerung, bietet einen breiten Anwendungsbereich, hohe Ausbeuten und funktionelle Gruppentoleranz und erhöht ...
