Reactivity Differences between α,β-Unsaturated Carbonyls and Hydrazones Investigated by Experimental and Theoretical Electron Density and Electron Localizability Analyses

Abstract: It is still a challenge to predict a compound's reactivity from its ground-state electronic nature although Bader-type topological analyses of the electron density (ED) and electron localizability indicator (ELI) give detailed and useful information on electron concentration and electron-pair localization, respectively. Both ED and ELI can be obtained from theoretical calculations as well as high-resolution X-ray diffraction experiments. Besides ED and ELI descriptors, the delocalization index is used here; it… Show more

“…[21] Hier werden erstmalig Informationen zur Bindungsordnung präsentiert, die auf experimentellem Wege gewonnen wurden, genauer gesagt aus einer hochaufgelçsten Rçntgenbeugungsmessung von kristallinem SO 2 bei niedriger Temperatur. [24] Die resultierende Wellenfunktion, die somit alle gemessenen Informationen enthielt, wurde dann mit verçffentlichten Methoden (Delokalisierungsindex d, [25] Roby-Bindungsindex t, [26] Elektronenlokalisierbarkeitsindikator ELI, [27] Atome-in-Molekülen-Ansatz (AIM) [17] ) analysiert, um so die für die Chemie wichtigen Bindungsinformationen zu erhalten. SO 2 wurde in situ unterhalb seines Schmelzpunktes auf dem Diffraktometer bei 118 K kristallisiert; Verbindung 1 wurde bei 100 K gemessen.…”

“…[27]), aber hier ist der Effekt ungewçhnlich stark ausgeprägt. Es gibt lediglich zwei freie Sauerstoffelektronenpaare pro Atom, aber jedes freie Elektronenpaarbassin ist mit 2.8 bis 3.0 e populiert; auch das freie Schwefelelektronenpaar ist mit 2.8 e hçher populiert als für ein einzelnes Elektronenpaar zu erwarten ist.…”
