Von Sauerstoff zu Tellur: Der Einfluss des Chalkogenatoms auf die Nucleophilie und Basizität von Isochalkogenharnstoff‐basierten Katalysatoren

Angewandte Chemie, Volume 137, Issue 48, November 24, 2025.
Der Einbau verschiedener Chalkogenatome (O, S, Se oder Te) in häufig verwendete Isochalkogenharnstoff‐Organokatalysatoren ermöglicht die Feinabstimmung ihrer Nucleophilie und Basizität. Kinetische und thermodynamische Deskriptoren für die molekularen Eigenschaften der Katalysatoren werden als Werkzeuge zur Vorhersage ihrer Effizienz eingeführt und in ...
