Exploring Mesoionic Imine‐Carbodiimide (MII‐CDI) Adducts: 1,3 H‐Shift, N(I) Compounds and Guanidinate‐Type Ligands

Angewandte Chemie International Edition, Volume 64, Issue 34, August 18, 2025.
We demonstrate the unique reactivity of a mesoionic imine with bis‐aryl carbodiimides, forming an MII‐CDI adduct at room temperature via a spontaneous 1,3‐H shift. These MII‐CDI adducts serve as important synthons for mesoionic carbene‐acyclic diamino carbene‐stabilized nitreones (I) and guanidinate‐type ligands.

An Atomically Dispersed Photocatalyst for Undirected para‐Selective C─H Bond Functionalizations

Angewandte Chemie, Volume 137, Issue 33, August 11, 2025.
This study presents an atomically dispersed recyclable heterogeneous photocatalytic method for para‐selective trifluoromethylation of electron‐deficient arenes without directing groups. Unlike previous substrate‐dependent approaches, this recyclable, atomically dispersed photocatalyst enables scalable synthesis of bioactive trifluoromethylated ...
