Chemoselectivity and Enantioselectivity in the Conjugate Reduction of Cinnamate Esters and a Tandem Conjugate Reduction‐Ester Hydrogenation Using Manganese Catalysts

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
An improved synthesis of a manganese catalyst used for hydrogenation of ketones, esters and imines is reported. The catalyst has now been found to effect tandem conjugate reduction‐ester hydrogenations with very low amounts of allylic alcohol by‐products.

One‐Dimensional Polycyclic Aromatic Hydrocarbons Incorporating Multiple Dithiafulvene Units—Novel Multi‐Redox and Electrochromic Systems

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Planar polycyclic aromatic hydrocarbons (PAHs) incorporating three or four dithiafulvene (DTF) units were synthesized via Horner–Wadsworth–Emmons reactions to create large π‐conjugated redox‐active frameworks. These molecules display strong intermolecular associations and distinct odd–even redox behavior, enabling formation of mixed‐valence and radical‐

Does Aromaticity Drive Metal Cation Binding to Nanographenes? Insights Into Regioselectivity and Cation‐π$$ \pi $$ Bonding

Journal of Computational Chemistry, Volume 47, Issue 10, 15 April 2026.
Aromaticity of a ring by itself does not explain the binding energies of alkali and alkaline earth metal cations with nanographenes, but when combined with the Fukui function, it does. ABSTRACT Nanographenes, a subclass of polycyclic aromatic hydrocarbons (PAHs), have attracted significant interest due to their unique electronic properties and broad ...

Impacts of Quinone Structure on Trade‐Offs Between Redox Potential and CO2 Binding Strength

ChemPhysChem, Volume 27, Issue 7, 14 April 2026.
Quinones are well‐studied and promising candidates for redox‐active sorbents in electrochemical CO2 capture and storage (ECCS). Unfortunately, reactivity with O2 is a persisting issue in the use of quinones. While attempts have been made to tune the redox‐potentials of quinones to avoid this, quinones which are more tolerant to the presence of O2, are ...

Chiral Heptagon‐Embedded Double [6]Helicenes via Scholl Reaction

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
One bond makes the difference–two chiral and twisted polycyclic aromatic hydrocarbons (PAHs) show different emission behavior. The more flexible one (top) shows a double emission with one having a large anti‐Stokes shift. The two peaks are assigned to different conformers of one and the same compound.

Dibenzazepin‐verbrückte Netzwerk‐Polymer‐Phthalocyanine als abbaubare heterogene Photokatalysatoren

Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.
Photodynamische Dibenzazepin‐Brücke wurde in Zink‐ und Kobalt‐Netzwerk‐Polymer‐Phthalocyanine (NP‐Pcs) eingeführt, um abbaubare heterogene Photokatalysatoren zu erhalten. Zum ersten Mal spielt die Bestrahlung mit Licht eine Schlüsselrolle beim „Design, der Verwendung und dem Abbau” von NP‐Pcs.
