Isotope effects reveal that para-substituted benzylamines are poor reactivity probes of the quinoprotein mechanism for aromatic amine dehydrogenase

open access: yes, 2007
Structure-activity correlations have been employed previously in the mechanistic interpretation of TTQ-dependent amine dehydrogenases using a series of para-substituted benzylamines.

Expeditious Synthesis of Phenanthridines from Benzylamines via Dual Palladium Catalysis

open access: yes, 2016
A method for the synthesis of phenanthridines from benzylamines and aryl iodides which uses a dual palladium-catalyzed process is developed. The domino sequence ends via an intramolecular amination and an oxidative dehydrogenation. No protecting group or

Bayesian Optimization of Solvent‐Free Thermal Amidation via Reactive Extrusion

open access: yesChemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
Thermal amidation between a carboxylic acid and an amine was successfully conducted in an extruder in the absence of solvent, coupling agent, or catalyst, relying on an adapted Bayesian Optimization protocol. Active pharmaceutical ingredient moclobemide was synthesized on a larger scale, achieving excellent yield and low Process Mass Intensity (PMI ...

Incorporating a DAD-Type Benzothiadiazole Photosensitizer into MOFs for Photocatalytic Oxidation of Phenylsulfides and Benzylamines

open access: yes, 2023
Oxidation and removal of highly toxic sulfides and amines are particularly important for environmental and human security but remain challenging. Here, incorporating an excellent photosensitizer, donor–acceptor–donor (D–A–D)-type 4,4′-(benzo[c][1,2,5 ...

Synthesis of 1,2,4-Trisubstituted-(1H)‑imidazoles through Cu(OTf)2‑/I2‑Catalyzed C–C Bond Cleavage of Chalcones and Benzylamines

open access: yes, 2018
1,2,4-Trisubstituted-(1H)-imidazoles have been synthesized by the Cu­(OTf)2- and I2-catalyzed unusual C–C bond cleavage of chalcones and benzylamines. After the α,β-unsaturated C–C bond cleavage, the β-portion is eliminated from the reaction.

Emerging Trends in Organic Photoreactions Utilizing Disulfides

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...
