Synthesis of Zwitterionic Tris(pyrazolyl) Ligands and Their Mn(II) Bis‐Chelates Exhibiting Charge–Transfer‐Induced Spin Crossover

European Journal of Inorganic Chemistry, EarlyView.
In this article, a series of zwitterionic scorpionate ligands based on the anionic tris‐(pyrazolyl)borate ligand scaffold is presented. These ligands are used to prepare bis‐chelates with divalent manganese ions. The resulting complexes are studied via magnetic, crystallographic, and electrochemical means to characterize the charge–transfer‐induced ...

π‐Extended Silyl Enolates as Emerging Platforms in Radical Chemistry

European Journal of Organic Chemistry, EarlyView.
This review covers the emerging role of π‐extended silyl polyenol ethers in radical chemistry. It highlights their versatile roles as electron‐rich SOMOphiles, silyl radical cation precursors, and nucleophilic partners in radical–polar crossover manifolds, while considering recent advances in photoredox catalysis, electrochemistry, and transition metal‐

Regioselective Oxidative Oligomerization of 2‐Tert‐Butylpyrene Toward Structurally Defined Oligomers and Their Application in Organic Light‐Emitting Diodes

European Journal of Organic Chemistry, EarlyView.
Treatment of 2‐tert‐butylpyrene with Cu2+ afforded structurally well‐defined pyrene oligomers, up to the 13‐mer. Single‐crystal X‐ray diffraction, spectroscopic analyses, and computational studies were conducted to evaluate the properties of the resulting oligopyrenes.

Chemoselective Aldehyde and Imine Reduction by a Macrocyclic Triazole–Borane Complex Triggered by a Non‐innocent Proton–Hydride Interaction

European Journal of Organic Chemistry, EarlyView.
This work describes the study on a new recyclable reagent, based on a macrocyclic triazole–borane complex. It showed high chemoselectivity for aldehyde reduction and reductive amination over ketones. This selectivity is driven by a noncovalent hydride–proton interaction that stabilizes the transition state for aldehydes but is sterically inhibited in ...

Selective N‐Functionalization of Pyrazoles

European Journal of Organic Chemistry, EarlyView.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

FlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).
