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.

VOCs Adsorption and Exchange Properties in Bispidine‐Based Mn(II) 1D CPs Made of Orthogonally Oriented Linear Chains

Chemistry – A European Journal, EarlyView.
Combining the chiral bispidine ligand L1 with MnCl2 affords coordination polymers (CPs) with an unusual topology for this family of compounds, consisting of orthogonally packed ribbon‐like one‐dimensional (1D) chains. Their behavior was investigated through single‐crystal‐to‐single‐crystal exchange with aromatic volatile organic compounds (VOCs) and ...

Mild C─F Activation of Azido(per)Fluoroalkanes

Chemistry – A European Journal, EarlyView.
Mild and selective activation of C(sp3)–F bonds in azido(per)fluoroalkanes using thiolates was developed, leading to novel functionalized azides. The reaction is initiated by nucleophilic attack of the sulfur atom to the terminal nitrogen of the azido group, followed by fluoride ion elimination.

Stereochemical Control in the Matteson Reaction

Chemistry – A European Journal, EarlyView.
The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Cyclopropylamine‐Derived Distonic Iminium Radicals: Photoinduced Strategies in Chemo‐ and Stereo‐Selective Synthesis

Chemistry – A European Journal, EarlyView.
Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

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.
