Next‐Generation Carbon‐Based Anodes for Alkali Metal‐Ion Batteries: Recent Progress on Biphenylene and Emerging Materials

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Recent advances in carbon‐based anodes for alkali metal‐ion batteries are critically reviewed, with emphasis on biphenylene and other emerging carbon allotropes. Biphenylene exhibits exceptional theoretical electrochemical properties beyond conventional graphite, highlighting its strong potential as a next‐generation anode material once scalable ...

From Olefin Coordination to Rh─N Bond Formation and Oxidative Addition: pH Effects in Rhodium α‐Methyl‐β‐Amidoitaconate Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The coordination of α‐methyl‐β‐amidoitaconate at Rh(I) diphosphine complexes is studied using a combination of high‐field and low‐field flow NMR spectroscopy and X‐ray analysis. In the presence of basic or acidic additives, the formation of neutral Rh(I) or Rh(III) complexes occurs.

Quantifying Anisole Dimer Interactions in Solution With a Molecular Balance

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Dispersion‐driven anisole stacking overcomes steric repulsion to favor folded cyclooctatetraene valence‐bond isomers in solution. We report a combined experimental and computational study that quantifies the interaction strength of anisole–anisole stacking in solution using a 1,4/1,6‐dianisole‐substituted cyclooctatetraene (COT) molecular balance.

Isotelluroureas for Asymmetric C1 Ammonium Enolate Reactions

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Chiral isotelluroureas are powerful catalysts for a variety of C─C bond forming C1 ammonium enolate transformations. Isotelluroureas (ITeUs) have recently been introduced as a novel class of highly nucleophilic Lewis base catalysts. Herein, we systematically screened them for their potential to facilitate C1 ammonium enolate transformations and ...

Diastereoselective Synthesis of Highly Substituted Methylene Cyclobutanes by Pd Catalysis

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A chemo‐ and diastereoselective palladium‐catalyzed intramolecular coupling/cyclization of borylated 1,5‐dienes, readily accessible by allene allylboration, with iodoarenes enables the synthesis of highly substituted methylene cyclobutanes. The method exhibits broad scope, high functional group tolerance, and complete enantiospecificity.

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Mechanistic Dichotomy in Enantioselective Pd‐Catalyzed Alkylation of Pyrroles With Diazoesters

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Ligand‐controlled mechanistic divergence controls the Pd‐catalyzed asymmetric alkylation of pyrroles with diazoesters. While bipyridine ligands promote a conventional metal‐carbene pathway, bipyridine‐N,N′‐dioxide ligands redirect catalysis through electrophilic CH metalation before carbene transfer.

Hydroformylation of Olefins With Paraformaldehyde Catalyzed by a Rhodium(I)/Diphosphine/Diphosphoramidite System

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A new dual‐ligand rhodium catalytic system based on [RhCl(cod)]2, BINAP or BIPHEP, and a diphosphoramidite ligand enables the hydroformylation of olefins using paraformaldehyde as a syngas surrogate. The system efficiently converts vinyl arenes, alkyl olefins, cyclopentene, and allyl acetate with high activity and regioselectivity.

Stereoselective and Diastereospecific Aminosilylation and Hydrosilylation of Heterobicyclic Alkenes by Copper Catalysis Under Mild Conditions

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An efficient and straightforward methodology for the stereoselective and diastereospecific aminosilylation and hydrosilylation of heterobicyclic norbornene derivatives is introduced. The mild conditions enable the functionalization of norbornene substrates with broad functional‐group tolerance.
