Silicon‐Bridged Homocyclopentadienides: Metal‐Assisted Facile Ring Expansion of Cyclopentadienide by Transient Imino(Metallophosphino)Silylenes

open access: yesAngewandte Chemie, EarlyView.
We demonstrate the facile aromatic C─C bond cleavage of cyclopentadienide mediated by transient imino(metallophosphino)silylenes, enabling the transformation of an aromatic system into a homoaromatic species. The steric bulk of the phosphino substituent, together with the weak interaction between the coinage metal and the cyclopentadienide ligand, are ...

High‐Pressure Synthesis of Quantum‐Stabilised Manganese Superhydride MnH7

open access: yesAngewandte Chemie, EarlyView.
Superhydrides are a rarity in transition metal hosts. Through high‐pressure, high‐temperature diamond anvil cell studies, the most hydrogen‐rich transition metal hydride, MnH7${\rm MnH}_7$ has been synthesised. Density functional theory calculations demonstrate that zero‐point energy stabilises the crystalline structure that MnH7${\rm MnH}_7$ adopts ...

Lichtgesteuerte Dosierung der PPARγ‐Aktivierung Mittels Schnell Relaxierender Photoschalter

open access: yesAngewandte Chemie, EarlyView.
Um eine räumlich‐zeitliche Kontrolle der PPARγ‐Aktivität zu ermöglichen, entwickelten wir den schnell relaxierenden photoschaltbaren Agonisten 6, der PPARγ selektiv in seinem lichtinduzierten Z‐Zustand aktiviert und innerhalb von Sekunden (t1/2 = 47 s) in den inaktiven E‐Zustand relaxiert.
