Mesoionic N‐Heterocyclic Olefins, Imines, Thiones, Phosphinidenes and Their Application in Catalysis

Angewandte Chemie International Edition, Volume 65, Issue 3, 16 January 2026.
This minireview covers recent advances in the synthesis, reactivity, and metal‐free catalytic uses of mesoionic N‐heterocyclic olefins (mNHOs), imines (mNHIs), thiones (mNHTs), and phosphinidenes (mNHPs). Abstract Transition metal compounds are widely known for their ability to activate small molecules and are excellent catalysts for a wide range of ...
