Conjugated Inorganic–Organic Hybrid Polymers with p‐Block Elements

Angewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
The influence of various p‐block element motifs on the photophysical properties of conjugated inorganic‐organic hybrid polymers is surveyed regarding applications in organic electronics. Recent advances in the use of heavier elements as well as heavier multiple bonds and the development of diverse (post‐)functionalization strategies suggest ample scope

Inverse‐Electron‐Demand Diels–Alder Reaction of Tropone with Graphene Supported on Cu(111)

Small, Volume 21, Issue 44, November 6, 2025.
The inverse‐electron‐demand Diels–Alder reaction between tropone and graphene supported on Cu(111), catalyzed by B(C6F5)3 or BPh3, gave [4 + 2] and [8 + 2] cycloadducts, respectively. Computations reveal that the cycloadditions become favorable on curved graphene with secondary substrate charge transfer effects and reveal the origins of the product ...

A Simple Method for Anchoring Silver and Copper Nanoparticles on Single Wall Carbon Nanotubes

Nanomaterials, 2019
Single walled carbon nanotubes (SWCNT) were functionalized using the 1,3-dipolar cycloaddition reaction of an azomethine ylide under solvent-free conditions, a one-pot procedure that yields pyrrolidine type of groups at the nanotubes surface.

Versatile Photofunctionalization of Carbon Nanotubes via [4 + 2] Cycloaddition: A Facile Route to Hybrid Nanomaterials

Small Science, Volume 5, Issue 11, November 2025.
A [4 + 2] photocycloaddition of aryl cyclobutyl amines on carbon nanotubes is presented. A photocatalyst oxidizes the cyclic moiety to generate an active species trapped by the nanotube π‐cloud. The method functionalizes nanotubes of different characteristics and is tolerant to different functional groups decorating the amine.

An Efficient Synthesis of Novel Dispirooxindole Derivatives via One-Pot Three-Component 1,3-Dipolar Cycloaddition Reactions

Molecules, 2012
A series of novel dispirooxindoles have been synthesized through three-component 1,3-dipolar cycloaddition of azomethine ylides generated in situ by the decarboxylative condensation of isatin and an α-amino acid with the dipolarophile 5-benzylidene-1,3 ...

Redrawing the Mannich‐Type Reaction through Carbonyl Umpolung Reactivity

Advanced Synthesis &Catalysis, Volume 367, Issue 20, October 29, 2025.
GA: Herein, a conceptually novel one‐pot multicomponent strategy is reported for the streamlined construction of five‐membered imidazolidines from 1,2‐diaza‐1,3‐dienes (onefold), amines (twofold), and formaldehyde (twofold). This redesigned Mannich‐type reaction that exploits a carbene‐like activity of 1,2‐diaza‐1,3‐dienes (realized by “umpolung ...
