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.

Electrochemical Three‐Component Synthesis of Heteroaryl Sulfonates
European Journal of Organic Chemistry, EarlyView.An electrochemical, metal‐free three‐component strategy for direct C(sp2)─H sulfonation of electron‐rich heteroarenes using SO2 and alcohols is described. Utilizing inexpensive graphite electrodes and practical SO2 stock solutions under mild conditions, this method provides straightforward access to heteroaryl sulfonates from simple building blocks ...

Hamiltonian analysis of BHT massive gravity [PDF]
, 2010 We study the Hamiltonian structure of the Bergshoeff-Hohm-Townsend (BHT) massive gravity with a cosmological constant. In the space of coupling constants (Λ0, m2), our canonical analysis reveals the special role of the condition Λ0/m2 ≠ −1.

Metal‐Free Ligand‐Centered Radical Scavenging in Pyridine‐Modified Tetraaza Macrocycles
European Journal of Organic Chemistry, EarlyView.Ligand‐centered hydrogen‐atom transfer in pyridinophane macrocycles generates delocalized radicals, with Py2N2 enabling cooperative captodative stabilization and enhanced DPPH• quenching. Pyridine‐modified tetraaza macrocycles are widely studied as ligand platforms for metal coordination, yet their intrinsic redox and radical reactivity in the absence ...
