A Phenazine‐Based Two‐Dimensional Covalent Organic Framework for Photochemical CO2 Reduction with Increased Selectivity for Two‐Carbon Products

open access: yesAngewandte Chemie, EarlyView.
The catalytic advantages of covalent organic frameworks (COFs) for sustainable CO₂ utilization have been demonstrated by the photocatalytic reduction of CO₂ by a redox‐active, phenazine‐based COF (Phen‐COF). Phen‐COF efficiently converts CO₂ into formate, oxalate, and carbon monoxide under light irradiation, achieving significantly higher yields than a

Imino‐Pyrrole Zn(II) Complexes for the Rapid and Selective Chemical Recycling of Commodity Polymers

open access: yesAngewandte Chemie, EarlyView.
Three imino‐pyrrole zinc (II) catalysts were prepared and applied to the chemical recycling of PLA, PET, and BPA‐PC. Rapid PLA degradation was accomplished in solution and under solvent‐free conditions, the latter giving full conversion at relatively mild temperatures after 11 min.

Routes to Pt Derivatives of High‐Valent Sulfur Oxofluorides S(═O)2F, S(═O)F2, and S(═O)F3 by Fluorination and Oxygenation

open access: yesAngewandte Chemie, EarlyView.
This study demonstrates the controlled functionalization of a SOF ligand at a platinum center, achieving the selective formation of SO2F and SOF2 complexes by fluorination or oxygenation. Further fluorination of the SOF2 ligand resulted in an unprecedented SOF3 metal derivative, which is a unique example of a high‐valent fluorinated sulfur atom ...
