Move over cyclopentadiene anion—there’s a new five-membered aromatic ring in town, and this one is made of silicon. Two research teams working independently report the first examples of pentasilacyclopentadienide—an all-silicon version of cyclopentadienides. cen.acs.org/materials/in... #chemsky 🧪
Aromatic 5-silicon rings synthesized at last
2 groups working independently construct the same long-sought compound via different routes

📣Our new paper is out in @jacs.acspublications.org (our very first one)!🥳 We show how a redox-active ligand unlocks C–X bond scission at an ambiphilic T-shaped Bi(III) compound. A big collaborative effort with my brilliant colleagues from Berlin. 👉 pubs.acs.org/doi/10.1021/...

New chapter ahead! After successfully defending my PhD @scheschkewitz.bsky.social, I moved to Toulouse for a postdoc @lbpblab.bsky.social I am grateful for the exciting experience, all support along the way (@chemieverband.bsky.social) and thrilled to now be working with even heavier elements!

Towards functionalized polymers with Ge=Ge bonds? The Ge-Si bonds of our NHC-bis(germylene) monomer react selectively with CO2 and RNCO under retention of the Ge(II) centers! Subsequent reaction with a CAAC results in a paramagnetic germylene! @scheschkewitz.bsky.social @munzgroup.bsky.social
