Boron‐Doping of a Macrocyclic Tetrafuran Framework Unveils an Expanded Porphyrinoid With Switchable (Anti)Aromaticity and Conformational Dynamics

open access: yesAngewandte Chemie, EarlyView.
We disclose a novel boron macrocycle derived from the sustainable furan building block. The boraporphyrinoid exhibits a global antiaromatic ring current and dynamic conformational flexibility. Twofold reduction induces a switch to strong global aromaticity, accompanied by stiffening of the porphyrinoid backbone.

Room‐Temperature Gas‐Phase CO2‐to‐C3 Coupling by a 4f‐Aromatic Cluster

open access: yesAngewandte Chemie, EarlyView.
We engineered a 4f metalla aromatic cluster, PrB2C2−, that enables efficient sequential C−C coupling with CO2 at room temperature, yielding a linear C3 backbone. This system provides a complete theoretical catalytic cycle and establishes a new design principle for lanthanide mediated CO2 activation.

Asymmetrische α‐Alkylierung mit aktivierten und unaktivierten Elektrophilen durch einen hocheffizienten und rezyklierbaren Lewis‐Säure/Imidazolium‐Katalysator

open access: yesAngewandte Chemie, EarlyView.
Ein luftstabiler, einfach herzustellender bifunktioneller Cu(II)/Imidazolium‐Komplex ermöglicht hoch enantioselektive α‐Alkylierungen von 1,3‐Dicarbonylverbindungen mit herausragender Produktivität (TON bis zu 1740). Zu den hervorzuhebenden Merkmalen zählen ein breites Elektrophilspektrum, das sowohl π‐aktivierte als auch nicht aktivierte Reagenzien ...
