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 ...

Deprotonative C(sp3)/C(sp2)–H (Multi)Silylation of (Hetero)Arenes Mediated by NaTMP

Angewandte Chemie, Volume 138, Issue 21, 18 May 2026.
An operationally simple protocol using a strongly basic sodium amide in combination with sterically emcumbered silicon electrophiles enables the deprotonative C–H (multi)silylation of a myriad of (hetero)arenes. Mechanistic investigations highlight the pivotal role of steric and coordination effects in controlling the regioselectivity and efficiency of

1,2‐Diazetidines − Structure, Synthesis, and Functionalization

European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

Expanded Scorpionate and Siderophore‐Inspired Ligands: From Foundational Designs to Modern Applications

European Journal of Inorganic Chemistry, Volume 29, Issue 15, 20 May 2026.
The concept of scorpionate ligands has evolved significantly since the introduction of tris(pyrazolyl)borate. By integrating a biological supramolecular ligand scaffold with the classic scorpionate architecture, researchers have made notable strides in mimicking the active sites of nitrogenase and advancing homogeneous catalysis.

Phosphorescent Platinum(II) Complexes With Diazinedipyrrolide Pincer Ligands: Structure and Photophysical Properties

European Journal of Inorganic Chemistry, Volume 29, Issue 15, 20 May 2026.
A new family of phosphorescent Pt(II) complexes with pyrimidinedipyrrolide ligands, including a pyrazine analog, was designed and synthesized. Their emission properties can be finely tuned via ligand modification, revealing strong phosphorescence originating from intraligand charge transfer transitions.

Mild and Metal‐Free CH Arylation of Imidazoles via In Situ Diazotization in Water

Advanced Synthesis &Catalysis, Volume 368, Issue 10, 19 May 2026.
Imidazoles undergo direct C–H arylation through in situ generated diazonium salts in water, under ambient and catalyst‐free conditions. This operationally simple method avoids hazardous intermediates, tolerates sensitive functional groups, and preserves C–halogen bonds.
