Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Visible‐Light‐Promoted, (Photo)catalyst‐Free Synthesis of 3‐Sulfonyl‐Azaspiro[4.5]trienones via Arylazo Sulfones

European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
A set of 3‐sulfonyl‐azaspiro[4.5]trienones have been obtained via a metal‐ and photocatalyst‐free visible‐light‐driven dearomative strategy. The protocol exploits arylazo sulfones, which act simultaneously as the light absorber and sulfonyl‐radical source, enabling ipso‐spirocyclization of differently substituted N‐aryl propiolamides.

Interface Passivation and Enhanced Charge Transport With a Triphenylamine Self‐Assembled Molecule in Inverted Perovskite Solar Cells

Solar RRL, Volume 10, Issue 9, 13 May 2026.
A nonplanar triphenylamine‐based self‐assembled molecule is developed as an efficient hole‐selective contact for p–i–n perovskite solar cells. Its molecular geometry reduces interfacial density of defects on the perovskite and enhances hole‐extraction efficiency.
