Bis(2‐Adamantyl)Magnesium: Synthesis, Structure, and Applications of a Versatile and Shelf‐Stable 2‐Adamantyl Anion Equivalent

Chemistry – A European Journal, EarlyView.
At last, the long‐sought bis(2‐adamantyl)magnesium reagent has been prepared in high yield as a stable tetrahydrofuran/dioxane adduct and fully characterized by x‐ray crystallography. This potent nucleophile outperforms the corresponding Grignard in transmetallation and carbonyl addition reactions, opening new avenues in adamantyl organometallic and ...

Accurate Molecular Size Determination by Diffusion Ordered NMR Spectroscopy Based on an Improved Diffusion Model

Chemistry – A European Journal, EarlyView.
A semi‐empirical Stokes‐Einstein‐based model for describing the diffusion of organic, organometallic and coordination compounds is developed for the interpretation of diffusion constants obtained by diffusion‐ordered NMR spectroscopy (DOSY). This model uses the molecular volume as a descriptor and shows a high accuracy, enabling application to ...

Dioxygen Reduction at a Cu(I) Complex Supported by a Macrocyclic N3O Ligand System

Chemistry – A European Journal, EarlyView.
A non‐reactive [CuI(14‐TMC)]+ complex is transformed to an efficient catalyst [CuI(14‐TMCO)]+ (TMCO = 4,8,12‐trimethyl‐1‐oxa‐4,8,12‐triazacyclotetradecane) for 4e−/4H+ reduction of O2 by N → O substitution. ABSTRACT CuI(14 TMCO) (1), involving a N3O‐macrocycle, reacts with O2 at cryogenic temperatures to yield an end‐on peroxodicopper(II) species.

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments

Chemie Ingenieur Technik, EarlyView.
This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

On the defence of responsible human judgement in peer review

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Peer review is essential for scientific progress. When it works well, it combines expertise, fairness, proportionality, skepticism, generosity, and discretion. When it fails, it becomes a theatre for egotistical display, laziness, coercion, and, lately, reliance on artificial intelligence tools. Editors, reviewers, and authors must join forces
