Synthesis of 1,2,3-triazole functionalized hyperbranched poly(ethyleneimine) and its use as multifunctional anionic macroinitiator for diglycidyl ether of bisphenol A curing [PDF]
, 2016 Hyperbranched poly(ethyleneimine) (PEI) has been modified by the addition of propargyl acrylate following a Michael addition reaction. On this polymer (PEI-yne) a copper (I)-catalyzed azide alkyne cycloaddition (CuAAC) has been performed to obtain a ...

Development of a Copper‐Free Click Reaction for Asymmetric Rh Diene Catalysis Under Confinement
Advanced Synthesis &Catalysis, Volume 368, Issue 1, January 2026.A copper‐free amino–yne click reaction enables the selective functionalization of chiral diene ligands with both soluble and immobilized amines. Substituent‐controlled stereoselectivity affords (E)‐ and (Z)‐enaminone ligands, which are converted into Rh complexes for asymmetric catalysis under homogeneous and heterogeneous conditions.

ChemistryEurope, Volume 4, Issue 1, January 2026.From a modular synthesis of nonphosphine chiral nitrogen‐based chiral imidazoline–amino acid ligands, two new chiral imidazoline–proline‐copper catalysts are developed for targeting exo‐selective [3 + 2] cycloaddition reaction. Density functional theory studies rationalize the observed stereoselectivity and the distinct chiral pockets of the two ...

Journal of Chemistry, Volume 2026, Issue 1, 2026.Isophorone is an important motif in synthetic organic chemistry, as it is highly reactive and can get involved in a diverse array of functional group transformations to access various synthetic intermediates and molecular targets. In this context, an important group of compounds is the conjugated or nonconjugated isophorone‐cored dienones, which are ...
