Chemistry – A European Journal, EarlyView.A newly synthesized bifunctional azide—diazonium linker allows robust one‐step introduction of azido groups to single‐wall carbon nanotubes. Versatility of the azido groups as reactive handles is demonstrated by further derivatization with 6‐carboxyfluorescein and oligonucleotides.

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.

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids
Chemistry – A European Journal, EarlyView.This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...

New syntheses of aziridines and azirines.
, 1970 The work presented in this thesis concerns the oxidation of N-amino compounds and the interception of the reactive intermediates, the postulated amino-nitrenes. The Introduction has been divided into three parts concerning (1) the synthesis of aziridines

Synthesis and ring openings of cinnamate-derived N-unfunctionalised aziridines
Beilstein Journal of Organic Chemistry, 2012 tert-Butyl cinnamates are aziridinated with high trans-selectivity by an N–N ylide generated in situ from N-methylmorpholine and O-diphenylphosphinyl hydroxylamine.

Chiral Pyrazolinylidene Complexes for Asymmetric Catalysis
Chemistry – A European Journal, EarlyView.The synthesis and application of pyrazolin‐5‐ylidene NHC chiral‐at‐ruthenium catalysts is reported. The strong donating pyrazolin‐5‐ylidene ligands led to highly electron rich ruthenium complexes, which showed excellent catalytic activity and enantioselectivity in the intramolecular aziridination of an alkene.

Synthesis of N–H Aziridines from Unactivated Olefins Using Hydroxylamine-O-Sulfonic Acids as Aminating Agent [PDF]
Herein, we presented a practical methodology for the intermolecular aziridination of alkenes, using HOSA as the aminating agent, alongside pyridine or piperidine as the base, within HFIP solvent system.
