University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

A Free N‐Heterocyclic Carbene and Its Metal Complex

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Free N‐heterocyclic carbenes (NHCs) are directly visualized on ultrathin sodium‐chloride films on gold (NaCl/Au(111)) using scanning tunneling microscopy (STM), atomic force microscopy (AFM), and density functional theory (DFT). Submolecular imaging reveals their structure and frontier orbital.

Dimethyl‐, Diethyl‐, and Propylene Carbonates: An Emerging Class of Green Solvents for Organic Synthesis

The Chemical Record, EarlyView.
This review highlights recent advances in the use of organic carbonates, dimethyl carbonate (DMC), diethyl carbonate (DEC), and propylene carbonate (PC), as solvents in organic synthesis. Based on over seventy studies from the past 6 years, it shows their application in different organic reaction types, emphasizing their role in safer and more ...

A Neutral Linear Cobalt(I) Silylamide as a Platform for Alkyne Cyclotrimerization and an Intermediate‐Spin Imido Cobalt Complex

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
A new ly synthesized is employed in cyclotrimerisation of diphenylacetylene and platform for an imido cobalt complex. The imidocomplex is found in an intermediate‐spin state w ith an ambiguous electronic situation. Additional computational analyses hint to ananionic charge of imido complexes as a benefactor for a high‐spin state.

Facile Access to N‐Substituted Pyridyl Ligands

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A modular, robust, and versatile Buchwald–Hartwig amination protocol that enables the rapid synthesis of bipyridine, phenanthroline, terpyridine, and pybox ligands bearing dialkylamine, diarylamine, and heteroaromatic N‐substituents. Pyridyl motifs equipped with N‐substituents can be powerful ligands for catalysis, yet their broader adoption is limited
