Enhanced CO2 Electroreduction Through Electrostatic Functionalization of Iron Porphyrin

ChemCatChem, EarlyView.
This study introduces an iron porphyrin catalyst for CO2 reduction, featuring an ortho‐positioned imidazolium group designed to probe electrostatic effects. The catalyst exhibits a 100‐fold increase in activity over its unsubstituted counterpart at similar potentials.

Synthesis and Characterization of π‐Extended Azulenes via Nucleophilic Substitution and Intramolecular Cyclization of 5‐Alkynyl‐6‐Fluoroazulenes

ChemistryEurope, EarlyView.
A modular synthetic approach enables the preparation of azulene‐fused heterocycles via nucleophilic aromatic substitution followed by intramolecular cyclization of alkynyl fluoroazulenes. The method allows the incorporation of various heteroatoms (N, O, S, Se, and Te), leading to structurally diverse heteroannulated azulenes.

Easier, Safer, and Greener: Unlocking the Power of Solid Reagents in Organic Reactions by Mechanochemistry

ChemistryEurope, EarlyView.
This review highlights the powerful synergy between mechanochemistry and solid reagents to replace hazardous substances traditionally used in organic synthesis. Such an approach offers a safer and more sustainable pathway for conducting organic reactions, with potential benefits in both reactivity and selectivity. The use of solid bases, acids, and gas
