From Molecule to Material: How Support Changes Heterobimetallic Catalysts in Lactide Polymerization

Macromolecular Rapid Communications, EarlyView.
Silica‐supported heterobimetallic alkoxide complexes were developed as catalysts for lactide ring‐opening polymerization. Grafting iron‐based ate complexes onto SiO2‐700 produced well‐defined active sites, enabling controlled polymerization with predictable molar masses, narrow dispersities, and recyclability.

Thermometer Ions, Internal Energies, and In‐Source Fragmentation in Ambient Ionization

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Ionization and fragmentation are at the core of mass spectrometry. But they are not necessarily separated in space, as in‐source fragmentation can also occur. Here, we survey the literature published since our 2005 review on the internal energy and fragmentation in electrospray ionization sources.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

NMR‐Based Structural Analysis of Highly Substituted Pyridines From Kondrat'eva Aza‐Diels–Alder Cycloadditions

Magnetic Resonance in Chemistry, EarlyView.
We report the results from a kinetic and mechanistic investigation of an inverse‐electron‐demand Diels–Alder (IEDDA) cycloaddition involving an oxazole‐type diene synthesized via an Ugi–Zhu multicomponent reaction (UZ‐3CR). ABSTRACT Pyridines are a crucial class of heterocycles with widespread applications in natural products, pharmaceuticals, and ...

Ruthenium‐Catalyzed CH Alkenylation of Trypanocidal Naphthoquinones: A Mechanistic Benchmarking Study

ChemistryOpen, EarlyView.
Computational roadmap to click‐ready quinones. Quantum chemical analysis reveals how substituents modulate the reactivity of trypanocidal naphthoquinones in Ru‐catalyzed CH alkenylation, guiding the design of sulfonyl‐fluoride scaffolds for next‐generation antiparasitic agents.
