Catalyst‐Directed Selectivity in Vinylcarbene Reactions: A Comparative Study of Ag, Rh, and Cu Complexes

Advanced Synthesis &Catalysis, Volume 367, Issue 15, August 26, 2025.
This study reveals that ligand stereoelectronic effects, rather than vinylogous electrophilicity, govern selectivity in Ag‐, Rh‐, and Cu‐catalyzed vinylcarbene C(sp3)H insertions. These insights guide the design of more selective catalysts for CH functionalization.

Rational Control of C–N Axial Chirality in Bis‐Pentatomic N‐Pyrazolyl Maleimides through an Experimental and Computational Approach

European Journal of Organic Chemistry, Volume 28, Issue 31, August 22, 2025.
The configurational stability of a series of axially chiral bis‐pentatomic compounds of the N‐pyrazolyl maleimide scaffold has been investigated through a combined theoretical and experimental approach. The experimental values of the barriers to enantiomerisation of the title compounds are determined through dynamic high performance liquid ...

Dinuclear Benzene Linker Bis(pyrazolyl)amine Cobalt(II) Complexes and their Application as Selective Ethylene Dimerization Catalysts

European Journal of Inorganic Chemistry, Volume 28, Issue 22, August 20, 2025.
Dinuclear (pyrazolyl)amine cobalt(II) complexes are synthesized and structurally characterized. Activation of these cobalt(II) complexes with EtAlCl2 cocatalyst affords highly active and selective ethylene dimerization catalysts. The steric parameters induced by the pyrazolyl substituents largely influence both the catalytic activity and selectivity of
