Chemistry – A European Journal, EarlyView.Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Polysilane‐Supported Nickel as an Efficient Catalyst for the Hydrogenation of Aromatic Compounds†
Chinese Journal of Chemistry, EarlyView.A Ni/Si catalyst obtained from the reaction of poly(monohydro)silane with Ni(cod)2 serves as an effective heterogeneous catalyst for the hydrogenation of arenes under reaction conditions that are significantly milder than those required for conventional nickel‐based catalysts such as Raney nickel.

Probing the mechanism of electron capture and electron transfer dissociation using tags with variable electron affinity [PDF]
, 2009 Electron capture dissociation (ECD) and electron transfer dissociation (ETD) of doubly protonated electron affinity (EA)-tuned peptides were studied to further illuminate the mechanism of these processes. The model peptide FQpSEEQQQTEDELQDK, containing a

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

European Journal of Inorganic Chemistry, EarlyView.The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, EarlyView.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...
