Selective Oxidation of Primary Amines to Nitriles Catalyzed by the Ru‐Doped Hexagonal Perovskite SrMnO3

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
The selective oxidation of primary amines to generate nitriles provides a cost‐effective and atom‐economical synthetic approach that avoids the formation of harmful byproducts. However, achieving high yields under mild conditions remains challenging, due to the difficulty in efficiently activating the α‐CH bonds of amines and the multiple competing ...

Hollow Microporous Organic Networks Bearing Triphenylamines and Anthraquinones: Diffusion Pathway Effect in Visible Light-Driven Oxidative Coupling of Benzylamines

, 2015
Hollow microporous organic networks were prepared by using silica spheres as the template and tris­(4-ethynylphenyl)­amine and 2,6-diiodo-9,10-anthraquinone as the building blocks for the Sonogashira coupling.

Imidazole synthesis by transition metal free, base-mediated deaminative coupling of benzylamines and nitriles

, 2017
An unprecedented transition metal free, base-mediated deaminative coupling of benzylamines and nitriles is reported. This protocol provides a practical strategy for the synthesis of 2,4,5-tri-substituted imidazoles with liberation of NH3.

Three-Component Reaction of Benzylamines, Diethyl Phosphite and Triethyl Orthoformate: Dependence of the Reaction Course on the Structural Features of the Substrates and Reaction Conditions

Molecules, 2017
The reaction between benzyl amines, triethyl orthoformate, and diethyl phosphite affords either bisphosphonic (compound 1) or N-benzylaminobenzylphosphonic (compound 2) acid depending on the reaction conditions.

Monoamine Oxidase and Cholinesterase Inhibition Profiles of Semicarbazone and Thiosemicarbazone Derivatives

Chemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Thiosemicarbazones generally show higher MAO‐B inhibitory potential than their corresponding semicarbazones, and particularly T6 is the most potent, which contains R = H and X = S in its Tail Unit, with an IC50 value of 6.45 µM with SI of 3.6. ABSTRACT Twenty semicarbazone and thiosemicarbazone derivatives (T1–T20) were synthesized and evaluated for ...

Unlocking Heterobimetallic Architectures in a Symmetric PNNP Ligand Environment

Chemistry – A European Journal, Volume 32, Issue 21, 1 June 2026.
A symmetric PNNP ligand enables the modular assembly of heterobimetallic ZnRu and CoRu complexes from a mononuclear Ru(II) precursor. Ligand deprotonation triggers dearomatization and contraction of the metal–metal distance. Combined DFT and QTAIM analyses reveal metallophilic interaction in CoRu but not in ZnRu, highlighting controllable geometric and
