Mild C─F Activation of Azido(per)Fluoroalkanes

Chemistry – A European Journal, EarlyView.
Mild and selective activation of C(sp3)–F bonds in azido(per)fluoroalkanes using thiolates was developed, leading to novel functionalized azides. The reaction is initiated by nucleophilic attack of the sulfur atom to the terminal nitrogen of the azido group, followed by fluoride ion elimination.

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

Chemistry – A European Journal, EarlyView.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Chiral Pyrazolinylidene Complexes for Asymmetric Catalysis

Chemistry – A European Journal, EarlyView.
The synthesis and application of pyrazolin‐5‐ylidene NHC chiral‐at‐ruthenium catalysts is reported. The strong donating pyrazolin‐5‐ylidene ligands led to highly electron rich ruthenium complexes, which showed excellent catalytic activity and enantioselectivity in the intramolecular aziridination of an alkene.

Electrochemiluminescence of Heteroleptic Iridium(III) Complexes Featuring Substituted 2,4‐diphenylpyridinato Ligands

Chemistry – A European Journal, EarlyView.
Five heteroleptic iridium(III) complexes bearing cyclometalated 2,4‐diphenylpyridinato ligands were synthesized and their electrochemiluminescence (ECL) investigated. Two different coreactants were evaluated: tri‐n‐propylamine and benzoyl peroxide under anodic and cathodic potentials, respectively.

β‐Ketonitrile‐Modified Prodan Derivatives as Large‐Stokes‐Shift Solvatochromic Fluorophores With Enhanced Brightness and Ratiometric Thermometric Response

Chemistry – A European Journal, EarlyView.
We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.
