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.

Expanding Cyanide‐Bridged Weakly Coordinating Anions Through the Brominated Silver Salt Ag[BCNBBr]

Chemistry – A European Journal, EarlyView.
The brominated weakly coordinating anion [μ‐(CN)(B(C6F4Br)3)2] ([BCNBBr]−), based on two B(C6F4Br)3 units bridged by cyanide, is obtained as its silver salt Ag[BCNBBr] from CH2Cl2. Ag[BCNBBr] enables oxidation and halide abstraction reactions, affording diverse [BCNBBr]− salts with oxidizing and electrophilic cations.

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

Chemistry – A European Journal, EarlyView.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

Chemistry – A European Journal, EarlyView.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...

Deriving General Energy Predictors for Pnictogen Bonding

Chemistry – A European Journal, EarlyView.
This study derives general energetic predictors for pure pnictogen bonds from nitrogen to bismuth based on the potential energy density at the bond critical point. The research highlights the increasing occurrence of secondary interactions for heavier elements.
