Concise Total Syntheses of Leuconoxine‐Type Alkaloids Enabled by Palladium/Norbornene‐Catalyzed Pyrrole Difunctionalization

Angewandte Chemie, EarlyView.
Concise total syntheses of five leuconoxine alkaloids have been achieved using a pyrrole‐centered strategy, which features a newly developed palladium/norbornene‐catalyzed pyrrole double C─H functionalization method, a divergent late‐stage oxidative dearomatization tactic, and no use of protecting groups.

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

Angewandte 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

Angewandte 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

Angewandte 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 ...

Low‐Symmetry Face‐Capped Fe(II) Tetrahedra Through Anisotropic Ligand Extension

Angewandte Chemie, EarlyView.
A strategy for the formation of low‐symmetry face‐capped Fe(II) tetrahedra using anisotropic ligand extension is reported. The degree of distortion in the resulting tetrahedra correlates to the stability of the assemblies and the oxidation potentials of their metal ions. Abstract Low‐symmetry cages are attractive metallo‐supramolecular targets, as they

Polyphosphorus Ligand Complexes of Coinage Metals for Multiple Capturing of Intact P4 Tetrahedra

Angewandte Chemie, EarlyView.
Self‐assembly reactions of [CpRFe(η5‐P5)] (CpR = C5(CH3)5 and C5(4‐EtC6H4)5) with coinage metal salts and white phosphorus afforded an unprecedented novel class of mixed polyphosphorus ligand complexes in which metal ions multiply coordinate intact P4 tetrahedra.
