Indole‐Based π‐Extended Monophosphine Ligands for Enhanced Palladium‐Catalyzed Sonogashira Coupling

Journal of Heterocyclic Chemistry, EarlyView.
A general palladium‐catalyzed Sonogashira cross‐coupling of (hetero)aryl chlorides with aliphatic, (hetero)aryl alkynes is described using Pd(dba)₂/PCy2‐Napdole‐phos catalyst system. The reaction protocol exhibits broad substrate scope and the catalyst loading can be down to 0.2 mol% Pd.

Influence of the Cr to Ti Ratio on the High‐Temperature Oxidation Behavior of TaMoCrTiAl Complex Concentrated Alloys in Nitrogen‐Free Atmospheres

Materials and Corrosion, EarlyView.
Ta‐Mo‐Cr‐Ti‐Al refractory high‐entropy alloys show atmosphere‐dependent oxidation performance based on Cr:Ti ratios. Cr‐rich compositions excel in dry oxygen through continuous chromia formation, while Ti‐rich alloys perform better in humid conditions due to reduced chromium volatilization and hydrogen uptake effects.

Catechol‐Containing Poly(2‐isopropyl‐2‐oxazoline): Synthesis and Thermoresponsive Behavior in Aqueous Salt Solutions

Macromolecular Rapid Communications, EarlyView.
Polymers carrying catechol groups are interesting mussel‐inspired materials for wet adhesion applications or metal ion complexation for wastewater treatment. Here, catechol‐containing poly(2‐isopropyl‐2‐oxazoline)s were synthesized via microwave‐assisted cationic (co)polymerization and examined with regard to their thermoresponsive LCST behavior in ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Engineering Pd Nanostructures on Hierarchical Flower‐Like Alumina Nanosheets for the Efficient Catalytic Reduction of 4‐Nitrophenol

Nano Select, EarlyView.
Palladium nanocubes and nanoparticles supported on nanosheet‐assembled alumina (NA‐Al2O3) were investigated as highly efficient catalysts for the reduction of 4‐nitrophenol. Systematic comparisons highlight the roles of nanoparticle morphology and support structure, with PdNC@NA and PdNP@NA showing superior activity and stability over commercial Al2O3 ...
