Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Modulation of Epigenetic Control by Advanced Molecular Tweezers

Chemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

Persilylated and Related Silyl Anion‐Induced Synthesis of Group 3–10 Metal–Silyl Complexes

Chemistry – A European Journal, EarlyView.
Persilylated and related silyl anions serve as powerful tools for constructing metal–silyl complexes across group 3–10 elements. Their strong σ‐donating ability and steric bulk stabilize low‐coordinate, reactive species and enable unique bonding motifs.

A Self‐Enhanced Tandem Catalytic System for Olefin‐to‐Diol Conversion Powered by Single‐Atom Fe Catalysts With In Situ Generated Acid

EcoEnergy, EarlyView.
A single‐atom iron catalyst with well‐defined Fe–N4 sites enables a tandem epoxidation‐hydrolysis process for converting terminal olefins to 1,2‐diols. The in situ‐generated isobutyric acid drives the hydrolysis step, affording broad substrate scope and excellent recyclability.
