From Phosphinimines to Four‐Membered SiCPN Cations: Insights Into N–Si Bonding and Ring Strain

European Journal of Inorganic Chemistry, EarlyView.
Sterically tuned N‐silyl phosphinimines enable four‐membered SiCPN cations. Hydride abstraction yields cyclic cations for Me and iPr substituents at silicon, while tBu gives a protonated intermediate. Multinuclear NMR spectroscopy, X‐ray crystallography, thermochemical density functional theory investigations, and natural bond orbital analyses reveal ...

Tracking the Reaction of Organoazides with Linear Chromium Silylamides

European Journal of Inorganic Chemistry, EarlyView.
The multifaceted outcome of the interaction of linear chromium silylamides with organoazides is presented. It leads to terminal and bridging imido complexes, as well as azide adducts. With acylazide, a terminal chromium oxide is obtained. The reaction of organoazides with a linear chromium(I) silylamide leads to the observation of rare monomeric and ...

Artificial [FeFe]‐Hydrogenase Mimics From Ferrocenyl Thioketone‐Functionalized Triphenylamine and (Bi)thiophene Derivatives: Synthesis, Characterization, and Hydrogen Evolution Catalysis

European Journal of Inorganic Chemistry, EarlyView.
Synthesis of ferrocenyl thioketone‐functionalized triphenylamine and triphenylamine‐(bi)thiophene derivatives as proligands for the assembly of artificial [FeFe]‐hydrogenase active site models. Thiocarbonyl compounds, especially thioketones, have emerged as promising precursors for constructing [FeFe]‐hydrogenase mimics that can mediate hydrogen ...

On the Planarity of Heterocyclic Bay‐Substituted Perylenediimides: Insight into the Fluorescent Photoinduced Electron Transfer Sensing Framework

European Journal of Organic Chemistry, EarlyView.
Near‐infrared fluorescent pH indicators based on perylenediimide were constructed in a modular receptor–spacer–fluorophore–spacer–receptor format with heterocyclic amino moieties at the bay positions. Counterintuitively, the dibrominated intermediate with two heavy atoms is more emissive than the heterocyclic compounds.

Synthesis and Reactivity of Iodepinium Salts

European Journal of Organic Chemistry, EarlyView.
An efficient oxidative cyclization of (Z)‐iodostilbenes grants access to the long‐elusive class of seven‐membered diaryliodonium salts — the iodepinium triflates. X‐ray analysis reveals their distinctly nonplanar geometry, while reactivity studies uncover unprecedented pathways, including copper‐mediated conversion to phenanthrene and chalcogen‐induced
