Acceptorless dehydrogenation and hydrogenation of N- and O-containing compounds on Pd3Au1(111) facets

Paul Joseph Dyson, Zhaofu Fei, Antoine Philippe Van Muyden, Zhangjun Huang, Xinjiang Cui, Tao Wang

Catalytic dehydrogenation and hydrogenation of amines and alcohols are important in the synthesis of fine chemicals. Despite several efficient homogeneous catalysts having been identified, highly active heterogeneous catalysts remain elusive, although they ...

Aromatic compounds containing triazenyl groups (N3RR′) have a profound impact on synthetic organic and medicinal chemistry. In contrast, the chemistry of vinyl and alkynyl triazenes was a largely uncharted territory until recently. The situation has change ...

2020

Triazenes are very useful compounds in organic synthesis, materials science, and medicine. Among numerous reported triazene derivatives, aryl triazenes are the most investigated. Triazenes with alkynyl, vinyl, and alkyl groups were, until recently, largely ...

Five-membered nitrogen-containing heterocyclic compounds (azoles) belong to potential moieties in complex structures where transformations during ozonation can occur. This study focused on the azole-ozone chemistry of pyrrole, imidazole, and pyrazole as mo ...

Applying a Trojan Horse Strategy to Ruthenium Complexes in the Pursuit of Novel Antibacterial Agents

Paul Joseph Dyson, Lucinda Kate Batchelor, Quentin François Antoine Laurent

Siderophores are iron chelators secreted by bacteria to scavenge iron(III) from their surrounding environment. They possess their own internalization pathway that is sufficiently unselective to be hijacked, making them suitable for Trojan Horse strategy ap ...

Divergent Asymmetric Synthesis of Polycyclic Compounds via Vinyl Triazenes

Rosario Scopelliti, Kay Severin, Nicolai Cramer, Gregor Kiefer, Abdusalom Suleymanov, Florian Gérald Abela, David Kossler

Vinyl triazenes were obtained by enantioselective [2+2] cycloaddition reactions of bicyclic alkenes with 1-alkynyl triazenes in the presence of a RuII catalyst with a chiral cyclopentadienyl ligand. These triazenes serve as unique vinyl cation surrogates. ...

Photoredox catalysis has been developed to achieve oxidative C-H chlorination of aromatic compounds using NaCl as the chlorine source and Na2S2O8 as the oxidant. The reactions occur at room temperature and exhibit exclusive selectivity for C(sp(2))-H bonds ...

Aerosol Health Effects from Molecular to Global Scales

Andrea Mario Arangio, Gerhard Lammel

Poor air quality is globally the largest environmental health risk. Epidemiological studies have uncovered clear relationships of gaseous pollutants and particulate matter (PM) with adverse health outcomes, including mortality by cardiovascular and respira ...

American Chemical Society2017

Control and prevention of environmental pollution has become a worldwide issue of concern. Aromatic hydrocarbons including benzene, toluene, ethyl benzene, xylene (BTEX) and polyaromatic hydrocarbons (PAHs) are persistent organic pollutants (POPs), release ...
