Etwa eine Billion Mal saurer als erwartet? Über den Unterschied zwischen der Hammett‐H0 und der vereinheitlichten pH‐Azidität der Schwefelsäure

Angewandte Chemie, Volume 137, Issue 52, December 22, 2025.
Runter mit der Brille! Mithilfe von Indikatorbasen wird die weit verbreitete Hammett´sche H0 Azidität bestimmt, mit der reine Schwefelsäure bisher charakterisiert wird. Das ist aber so ähnlich, als schaut man durch eine Sonnenbrille: trotz ihrer Nützlichkeit wirkt diese als Filter.

Bevorzugte Alkan‐Komplexierung: Kristallisation eines kationischen Mangan(I)‐Pentan σ‐Komplexes aus der Lösung

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Oxidation von Mn2(CO)10 unter pseudo‐Gasphasenbedingungen generiert den schwach koordinierten 16‐Valenzelektronenkomplex [Mn(CO)5]+ als Intermediat, der n‐Pentan binden kann, da dieses der am stärksten bindende Ligand im System ist. Drei Isomere dieses Komplexes wurden mit Tieftemperatur‐NMR‐Spektroskopie und Einkristall‐Röntgenbeugung untersucht.

Erinnerungskulturen in den Wissenschaften – eine Frage hegemonialer Narrative?

Berichte zur Wissenschaftsgeschichte, Volume 47, Issue 1-2, Page 128-150, June 2024.
Abstract Individual and institutional memories tend to form hegemonic narratives that serve to create identity and meaning. If history is written by experts and not by professional historians, historical retrospectives and narratives are usually written by leading figures in a particular field.
