Backbone double‐mutant cycle analysis quantifies hydrogen‐bond energies in proteins

Protein Science, Volume 35, Issue 6, June 2026.
Abstract Protein structure is stabilized by a variety of noncovalent interactions, but many remain incompletely understood. For example, several potentially ubiquitous interactions involving the protein backbone have been identified, but challenges in determining reliable experimental energies have prevented their integration into structural models.

Rapid Detection of Plasticizer Migration From UV‐Aged PVC Films by DART‐HRMS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale The migration of phthalate plasticizers from high‐volume polymers, such as poly(vinyl chloride) (PVC), raises significant toxicological concerns, particularly when materials are subjected to aging and environmental stress. As traditional monitoring techniques rely on time‐consuming solvent extraction and chromatographic methods that ...

Achieving Near‐Complete Dechlorination of Poly(vinyl chloride) via Electrochemical Reduction

ChemSusChem, Volume 19, Issue 10, 27 May 2026.
A one‐pot controlled‐voltage electrolysis achieved up to 97% dechlorination of poly(vinyl chloride) using common plasticizers as redox mediators. The liberated chloride ions were oxidized at the anode and utilized in a subsequent arene chlorination, offering a route for repurposing the chlorine from PVC.

Expanded Scorpionate and Siderophore‐Inspired Ligands: From Foundational Designs to Modern Applications

European Journal of Inorganic Chemistry, Volume 29, Issue 15, 20 May 2026.
The concept of scorpionate ligands has evolved significantly since the introduction of tris(pyrazolyl)borate. By integrating a biological supramolecular ligand scaffold with the classic scorpionate architecture, researchers have made notable strides in mimicking the active sites of nitrogenase and advancing homogeneous catalysis.

Alkyl Bismuth Cations: Synthesis, Characterization, and Application as Z‐Type Ligands

Chemistry – A European Journal, Volume 32, Issue 18, 14 May 2026.
Rare examples of alkyl bismuth cations [BiR2(SbF6)] are presented, including cyclopropyl ligands and a bismacyclic structure. The bismuth‐centered Lewis acids act as Z‐type ligands toward the electron‐rich platinum atom in [Pt(PCy3)2], generating a set of metal‐only Lewis pairs. The structural and spectroscopic properties of these rare types of bismuth

“Naked” Divalent Metal Cations Stabilized by Weakly Coordinating Anions: Syntheses, Properties, and Emerging Applications

European Journal of Inorganic Chemistry, Volume 29, Issue 14, 14 May 2026.
The preparation of soluble and stable metal M2+ dications only stabilized by weakly coordinating anions, that is, M[WCA]2 salts, is an emerging field that, beyond its fundamental interest, holds promise in reactivity due to the high electrophilicity of the central M2+ center.
