Revisiting C4N4 Fluorophore: Theoretical Elucidation of the Origin of Fluorescent Properties of 2,5‐Diaminopyrimidines and Strategic Applications to Pd Detection

Chemistry – A European Journal, EarlyView.
A compact C4N4 fluorophore—comprising only four carbons and four nitrogens—shows structure‐dependent fluorescence that can be rationalized by TDDFT and AFIR analyses. Rational structural design controls whether emission is turned ON or OFF through computationally identified CI structures.

Boric Acid Post‐Modified [Al]ZSM‐5 Zeolites: Properties, Acidity, and Ethanol/Ethene Conversion

Chemistry – A European Journal, EarlyView.
The modification of MFI zeolites with boric acid leads to the formation of framework boron, unstable surface species, and unbound deposits. Relevant BAS for catalysis and access to pores are strongly reduced. The boric acid is removed upon converting C1 or C2 alcohols and ethene. ABSTRACT The effect of boric acid post‐modification on [Al]ZSM‐5 zeolites

Ion–Molecule Reaction Products as Probes and Precursors for Preparative Mass Spectrometry

Chemistry – A European Journal, EarlyView.
Ion–molecule reactions in the gas phase of mass spectrometers are important for preparative mass spectrometry because they (1) provide knowledge about the intrinsic reactivity of ions, helping to predict and control their reactivity at interfaces, and (2) generate new complex ions that can be mass selected and deposited on surfaces.

Copper‐ and Silver‐Catalyzed Reactions of Active Methylene Isocyanides: Facile Access to Highly Substituted Five‐ and Six‐Membered Heterocycles

Chemistry – A European Journal, EarlyView.
This review summarizes recent advances in copper‐ and silver‐catalyzed reactions of active methylene isocyanides for the synthesis of highly substituted five‐ and six‐membered heterocycles. Emphasis is placed on [3+n] cycloadditions, annulations, and asymmetric strategies, highlighting current limitations and future opportunities in heterocycle ...

Metal Nanoparticles on Halloysite Applied in Stereoselective Hydrogenation of Tetrasubstituted Alkenes

Chemistry – A European Journal, EarlyView.
Composite materials based on metal nanoparticles supported on a naturally occurring nanotubular clay, halloysite (HAL), led to the diastereoselective hydrogenation of tetra‐substituted alkenes under relatively smooth conditions, mainly oxazolidinone‐based heterocycles.
