N‐Heterocyclic Carbenes and N‐Heterocycles as Synthetic Reagents and Building Blocks
Chemistry – A European Journal, Volume 31, Issue 12, February 25, 2025.N‐heterocyclic carbenes (NHCs) have widespread applications in synthesis as organocatalysts or ligands for organometallic complexes. This Mini‐review article focuses on an important but often neglected area of their chemistry, where NHCs and their N‐heterocyclic precursors or derivatives have been used as stoichiometric reagents or building blocks in ...

European Journal of Organic Chemistry, Volume 27, Issue 43, November 18, 2024.The vicinal (hetero)aryl functionalization of unactivated alkenes through radical addition of a functional group followed by remote (hetero)aryl migration provides a valuable tactic to install an aromatic ring at a specific position. The migratory (hetero)aromatic ring can be initially tethered to either the alkene or the radical precursor. This review

Synthetic Strategies and Applications of Fluorine‐Containing Bridged Bicyclic Compounds
European Journal of Organic Chemistry, Volume 27, Issue 43, November 18, 2024.This Concept aims to highlight the recent advancements in the synthesis of fluorine‐containing bridged bicyclic compounds (BBCs). The synthetic strategies have been categorized based on the position of functionalization (i. e. bridge or bridgehead), as well as in the type of F‐containing motif introduced in the bicyclic core.
