Coordination Studies of a Triazole‐Substituted 3H‐1,2,4‐Diazaphosphole: CC and CN Bond Activation Induced by Cobalt(0) and Nickel(0) Complexes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Reactions of a triazole‐substituted 3H‐1,2,4‐diazaphosphole with electron‐rich cobalt and nickel complexes result in the selective cleavage of CC and CN bonds on the triazole, forming chelate complexes with the activated diazaphosphole ligand. The reactivity of the recently reported 3H‐1,2,4‐diazaphosphole 1 toward electron‐rich Ni and Co complexes ...

Novel Sulfonium Reagents for the Modular Synthesis of Spiro[2.3]Hexanes and Heteroatom‐Containing Analogues: Synthesis, Application, and Evaluation as Bioisosteres

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Strained spirocyclic spiro[2.3]hexane and its heteroatom‐containing derivatives, including previously underrepresented 5‐oxa‐1‐azaspiro[2.3]hexanes and 1,5‐diazaspiro[2.3]hexanes, were synthesized via a modular approach of insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into alkenes, carbonyls and imines.

Mesoionic N-Heterocyclic Olefins, Imines, Thiones, Phosphinidenes and Their Application in Catalysis. [PDF]

Angew Chem Int Ed Engl
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 ...

Amido‐Imidazolin‐2‐imine Zinc Complexes: Facile Preparation by Mild In Situ Deprotonation

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
A representative amino‐imidazolin‐2‐imine ligand enables the preparation of stable zinc N,N´‐chelate complexes via in situ deprotonation. This mild method generates only volatile side products and affords both zinc(I) and zinc(II) complexes in good yield and high purity.

Accessing Molecular Complexity from Methane and Other Gaseous Alkanes via Photocatalytic Cascade Cyclization

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
An iron‐catalyzed protocol for the cascade cyclization of N‐aryl and N‐benzoyl acrylamides promoted by methane and other gaseous alkanes is reported. The current protocol provides an efficient platform for the conversion of feedstock gaseous alkanes into complex and medicinally relevant N‐heterocycles.
