A Crystalline Ylide‐Stabilized Stibenium Cation
European Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.The isolation of a stibenium cation stabilized by two thiophosphinoyl‐tethered ylide groups is reported. The cation is accessible via salt metathesis of the metalated ylide with SbCl3 and features CSb single bonds, with lone pairs remaining localized at the ylidic carbon atoms.

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.Anionic high‐spin iron(II) imido complexes are catalysts for the hydrogen isotope exchange (HIE) reaction with pyridine as the substrate. The alkali metal counter‐cation plays critical roles in activating the substrate and facilitating deuteration. These complexes catalyze site‐selective α‐, α,β,γ‐, and β,γ‐deuteration of pyridine, where the counter ...

From [NHC─H]• to Persistent σ‐Complex Radicals: Photoinduced Radical Chemistry of Imidazolium Salts
Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.Visible‐light excitation of electron donor–acceptor (EDA) complexes between imidazolium salts and triarylamines enables controlled single‐electron transfer (SET) and reveals a family of carbene‐centered σ‐complex radical cations. Cryogenic electron paramagnetic resonance (EPR) captures the elusive [NHC─H]• intermediate and its thermal evolution into ...

Synthesis and Reactivity of Extremely Electron‐Poor Au(III) Complexes Bearing OTf− or NTf2− Ligands
Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.A new family of electron‐poor Au(III) cations bearing bistriflimide or triflate ligands is reported. These cations can undergo direct C─H metalation with simple arenes to give mono‐aryl cations. Subsequent addition of simple halide sources allows for reductive elimination of aryl halides, formally from Ar─H and X−. ABSTRACT The synthesis and structural
