A molecule with half-Möbius topology

University of Oxford chemists are part of a team that have developed a ring-shaped molecule with an unprecedented topology: the so-called half-Möbius.

Isolation of arylhalodiphosphenes: periodic trends in R–PP–X bonding (X = Cl, Br, I) For over a century, aryldiazonium halides have served as widely used building blocks within synthetic chemistry. They are vital intermediates in converting simple anilines to high-value products, incl...

Check out recent work from the Mehta group looking at structure of Ar-P=P-X molecules, the compositional all P analogue of aryldiazonium halides. Published in @chemicalscience.rsc.org Thanks @ukri.org @erc.europa.eu for funding!

Well the caution is actually for dianionic derivative, the radical hasn’t exploded… yet

Series of stable nitrogen radical chains synthesised These compounds may find uses as nitrene precursors

It sounds implausible but chains of 4 nitrogen atoms that are stable at room temperature for weeks have been created.

A neutral cyclic aluminium (I) trimer - Nature Communications Low oxidation state aluminium complexes have gained wide recognition as discrete and versatile 2-electron reductants, but neutral trimeric structures remain elusive. Here the authors report the synthe...

Absolutely thrilled to see our ( @bakewellgroup.bsky.social ) paper "A neutral cyclic aluminium (I) trimer" has been published in @natcomms.nature.com in its full typeset version! www.nature.com/articles/s41...

Our latest paper is out in Nature Comms describing the first Fe(I)-ketyl radical complex. Congratulations to Laura, Ryan, Adam and our collaborator David Robinson from Nottingham Trent.

Isolation of Potassium Bis(amido)diazadipnictogenide Salts The reaction of Zintl phases K3As7 and K3P7 were investigated with 1-azido-4-bromobenzene (4-BrC6H4N3) and found to yield potassium salts of substituted diazadipnictogen rings (general molecular fragm...

Catalytic Nitrous Oxide Degradation with Group 15 Clusters Nitrous oxide (N2O) is sometimes referred to as the forgotten greenhouse gas, but ignoring it would be a mistake. N2O has a greenhouse warming potential 300× that of CO2, and anthropogenic emissions a...

Check out recent work from the Mehta group published in @jacs.acspublications.org! In this work we find that low-valent clusters can tap into a -1/+1 redox cycle!
