Depolymerization and Reuse of Polycarbonates: Emerging Classes, Mechanisms and Challenges

Angewandte Chemie, EarlyView.
This review collects the latest developments in the area of chemical and catalytic polycarbonate recycling strategies and includes the controlled degradation of similar types of macromolecules. Apart from the main strategies for deconstruction, the key mechanistic features of these depolymerization processes are also discussed together with the ...

Iron Catalyzed Aryl–Aryl Kumada Cross‐Coupling: A Mechanistic and Computational Investigation

Angewandte Chemie, EarlyView.
Despite intense interest, the mechanism of iron‐catalyzed aryl–aryl cross‐coupling remains poorly understood. Combining Mössbauer spectroscopy, kinetics analysis, and DFT computations these studies reveal a novel Fe(I)/Fe(II)/Fe(III) catalytic for aryl–aryl cross‐coupling mediated by an Fe(II) PCNHCP Pincer complex. These findings close a key knowledge

Conformationally Driven Dual Fluorescence Properties of Higher Heteroacenes With Periodically Incorporated Boron Atoms

Angewandte Chemie, EarlyView.
We herein report the synthesis of a new heteroheptacene derivative with periodically incorporated six boron atoms. This compound exhibits dual fluorescence attributed to two interconvertible conformers that result from a delicate balance between the extended π‐system and the steric demand of bulky aryl groups attached to the boron centers.

Induced Photoelectron Circular Dichroism as a Probe for Distinguishing Diastereotopic Lone Electron Pairs

Angewandte Chemie, EarlyView.
Gas‐phase complexation of chiral methyloxirane by achiral phenol results in induced chiroptical response of phenol. Two pseudo enantiomer complexes are observed, corresponding to hydrogen bonding from phenol to either of the lone electron pair of the methyloxirane oxygen, denoted as Pro R and Pro S, with opposite chiral deformation of phenol and ...
