Chemistry – A European Journal, EarlyView.We report an efficient method for late‐stage installation of “clickable” alkyne groups into diverse (hetero)arenes. Using a dual‐ligand palladium catalyst that combines an NASA ligand with an N‐heterocycle, an acrylate unit bearing a terminal alkyne can be introduced via nondirected C─H activation.

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...

European Journal of Organic Chemistry, EarlyView.Intramolecular cyclization to quench an in situ reduction‐generated azaquinone methide is a strategy that could be used for late‐stage heterocycle synthesis. Herein, synthetically accessible 4‐nitrobenzyl alcohols with a nucleophilic handle adjacent to the benzyl alcohol group are reduced under mild conditions to afford six‐ and seven‐membered ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Macromolecular Rapid Communications, EarlyView.Diacetylene‐containing glycan mimetics cluster upon selective lectin binding in GUVs. Subsequent irradiation leads to the formation of fluorescent polymer clusters, while non‐clustered glycan mimetics remain unaffected in the membrane. ABSTRACT The glycocalyx, a dense layer of glycoproteins and glycolipids on eukaryotic cells, is essential for cellular
