Gold(I)‐Mediated Reactivity of Allenes With Mesoionic Nucleophiles: A Computational Exploration

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
The regioselective gold(I)‐mediated reactivity of allenes with mesoionic nucleophiles has been evaluated through computational analysis of the mechanisms involved. Instead of typical (3 + 2) pathways, sydnones and münchnones favour the formal (3 + 3) cyclizations affording substituted dihydropyridines.

Isotellurourea‐Catalyzed Enantioselective (4+2)‐Heterocycloadditions of But‐2‐ynoates and Michael Acceptors

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
Isotelluroureas allow for the use of alkynoates for asymmetric (4+2)‐heterocycloadditions with different Michael acceptors. Alk‐2‐ynoates are readily available starting materials which, in principle, can be utilized for cycloadditions in analogy to structurally similar allenoates.

Masked Silylenes: Controlled Generation and Reactivity Under Thermal and Equilibrium Conditions

European Journal of Inorganic Chemistry, Volume 29, Issue 18, 22 June 2026.
This Review provides an overview of masked silylenes as bench‐stable precursors that release silylenes (R2Si:) under thermal activation or reversible equilibria. Precursor preparation, generation pathways, and characteristic reactivity are summarized, including trapping chemistry, reversible interconversions, insertion‐type processes, and small ...

1,1‐and 1,2‐Diborylalkenes: Preparation and Synthetic Applications

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
In this review, we highlight recent advances in the synthesis and reactivity of 1,1‐diborylalkenes and 1,2‐diborylalkenes, along with various transformations leading to C‐C, C‐heteroatom, and multicomponent products. By providing a comprehensive and practical resource, this review aims to assist researchers in exploring the synthetic utility of 1,1 and

Visible Light‐Induced Transformation of β‐Aryl‐α,β‐Unsaturated Acylsilanes into Indenol Derivatives via Alkenyl Siloxycarbenes

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
Visible light activates β‐aryl α,β‐unsaturated acylsilanes to form indenols without catalysts or metals. A stepwise photochemical cascade reorganizes simple precursors through isomerization, rearrangement, and ring formation. The process highlights sustainable reaction design while showcasing the synthetic power of acylsilane photochemistry and the ...

Stable Synapse‐Like Memory Switching in N‐Heterocyclic Carbene Monolayers

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
We report a redox‐active N‐heterocyclic carbene (NHC) monolayer showing synapse‐like behavior via proton‐coupled electron transfer (PCET). These quinone‐functionalized NHCs form dense self‐assembled monolayers and highly stable molecular junctions. Bias‐driven PCET switches quinone/hydroquinone states, producing reversible hysteresis and spike‐timing ...

Iodine‐Mediated Electrochemical Diastereoselective Synthesis of Enaminones

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
This work describes an efficient electrochemical (EC) method for transforming thioamides into enaminones via reaction with organic diazo compounds. The electrochemical approach is cost‐effective, mild, and proceeds through the in situ electrochemical generation of a copper complex.
