Routes to Cyclobutadiene and Cycloallyl Pt(II) Complexes: Dicationic Bis(Alkyne) Species as Intermediates

Chemistry – A European Journal, EarlyView.
This work demonstrates the synthesis of cationic Pt(II) η3‐cycloallyl complexes, and experimental and computational studies show a ligand bite‐angle dependence of their formation rates. The reactivity of these complexes with Brønsted acids was investigated, leading to the formation of cationic and dicationic Pt(II) η4‐cyclobutadiene complexes ...

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Diastereoselective Copper‐Catalyzed Defluorosilylation of Pentafluoroethyl Alkenes to Access Polyfluorinated Allylsilanes

Chinese Journal of Chemistry, EarlyView.
Under copper(I) catalysis, pentafluoroethylated alkenes can undergo smooth defluorosilylation to generate novel polyfluorinated products. The reaction exhibits high levels of diastereoselectivities for obtaining multisubstituted allylsilanes with control of the double bond geometry.

Intersecting Structures and Gendered Perceptions in Entrepreneurship: A Life‐Course Comparison of Institutional Inclusivity in Italy and the United Kingdom

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Using Global Entrepreneurship Monitor (GEM) 2024 data for Italy and the United Kingdom, this study examines how gender gaps in entrepreneurial perceptions, measured as perceived entrepreneurial skills and fear of failure, vary across age and education within contrasting institutional regimes.

Symbolic Versus Substantive ESG Practices: A Systematic Review and Integrative Framework

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT ESG reporting is widespread, but symbolic commitments do not always reflect substantive practices. This study conducts a systematic literature review of 62 empirical articles published between 2021 and 2025 to synthesize the main determinants and consequences of this disclosure–performance misalignment in ESG reporting (commonly referred to as

Novel Organelle‐Based Intracellular Immunity With Mechanistic and Therapeutic Implications

Barrier Immunity, EarlyView.
A conceptual framework illustrating how PAMPs/DAMPs initiate barrier, innate, adaptive, and intracellular immune responses, with organelle‐based intracellular immunity serving as a central integrator linking metabolism, inflammatory signaling, and therapeutic interventions to restore immune homeostasis.

Integrated numerical simulation and source‐sink matching methodology for Basin‐Wide CO2 storage assessment in depleted reservoirs: A Cambay Basin case study

Deep Underground Science and Engineering, EarlyView.
This study presents an integrated workflow to evaluate secure and large‐scale CO2 storage in depleted oil reservoirs of the Cambay Basin, India. Industrial CO2 sources are systematically matched with mature oil fields using a quantitative source–sink framework to minimize transport distance and cost.

Morphology Engineering Derived CoOOH With Tunable Oxygen Vacancies for Potential‐Dependent Selective Electrooxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Through a morphology engineering strategy applied to CoFe PBA precursors, we successfully fabricated the CoOOH active phase enriched with oxygen vacancies and abundant edge sites. The introduced oxygen vacancies not only enhance the strong adsorption capacity for oxygen‐containing substrates but also suppress the overoxidation of HMFCA, thus enabling ...

Well‐Defined Anilido–Imine Iron(II) Complexes for Catalytic Intramolecular Alkene Hydroamination of Primary Amines

European Journal of Organic Chemistry, EarlyView.
We synthesize and characterize a series of well‐defined anilido–imine Fe(II) alkyl complexes that demonstrate high activity and selectivity in the cyclohydroamination of unprotected primary amines tethered to unactivated alkenes. By tuning the steric and electronic parameters of the anilido–imine ligand, we develop a catalyst that outperforms ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...
