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

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
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.

N─H or O─H Bond Activation With a Bicyclic Si4 Ring Compound

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
The bicyclic Si4 ring compound with zwitterionic character reacts with NH3, H2O, and selected alcohols to give functionalized saturated silicon rings, siliconoid clusters with unsubstituted Si atoms, or simple 1,3‐addition products. The experimentally observed reactivity could be rationalized based on results from mechanistic calculations employing ...

1,3‐Bis(tetrylene)s: Emerging Platforms for Functional Main‐Group Molecules

European Journal of Inorganic Chemistry, Volume 29, Issue 28, 1 October 2026.
Bridge design governs the stability and reactivity of 1,3‐bis(tetrylene)s. This review surveys pnictogen‐, chalcogen‐, and tetrel‐bridged systems and shows how geometric preorganization and electronic communication can enable cooperative bond activation and access to unusual heavy‐element π frameworks. Main‐group chemistry has undergone a resurgence as

Facile Approach to Modulating Stereochemistry in Ring‐Opening Metathesis Polymerization of Cyclooctadiene

Journal of Polymer Science, Volume 64, Issue 19, Page 4037-4046, 1 October 2026.
The stereochemistry of polybutadiene made by ring‐opening metathesis polymerization (ROMP) evolves both during and after polymerization, as secondary metathesis shifts cis‐rich kinetic products toward trans‐rich equilibrium compositions. By tuning catalyst identity, additives, temperature, and reaction time, polybutadienes with 28%–80% trans content ...

Zero‐Valent Nickel Stabilized in Surface‐Supported Metal–Organic Chains

Angewandte Chemie International Edition, Volume 65, Issue 39, 21 September 2026.
9,10‐Dicyanoanthracene coordinates Ni atoms on Ag(100) to form metal–organic chains that stabilize zero‐valent Ni(0) (d10) centers with quasi‐one‐dimensional metal–ligand electronic coupling. ABSTRACT The stabilization of zero‐valent nickel Ni(0) centers in extended coordination networks remains a major challenge due to their pronounced reactivity and ...
