Second episode of our electride saga now out as a preprint on @chemrxiv.org. We have now moved from calcium to barium and added pulsed EPR to our arsenal, and we also show some pretty cool reactivity with arenes. Not quite Ba(I), but perhaps we are getting closer! chemrxiv.org/doi/full/10....

C-H activation and C-C coupling of arenes promoted by a room-temperature-stable barium amidinate electride | ChemRxiv

Carbon–carbon (C–C) coupling reactions are fundamental transformations in modern synthetic chemistry that are traditionally dominated by platinum group metal (PGM) catalysts. The scarcity, cost and toxicity of PGMs have inspired the quest for more ...

Delighted to announce the publication of our work in @nature.com, in collaboration with @nfchilton.bsky.social's group, on a dysprosium compound with magnetic memory at 100 Kelvin. Congrats to all authors inc. @gemmagransbury.bsky.social, @jeffjefftyjeff.bsky.social www.nature.com/articles/s41...

Soft magnetic hysteresis in a dysprosium amide–alkene complex up to 100 kelvin - Nature

A dysprosium amide–alkene complex shows soft magnetic hysteresis loops up to 100 kelvin, arising from the high charge density of the amide ligands and the structural role of the pendant alkene.

Just out: Synthesis, characterization and reactivity of a series of alkaline earth and rare earth iminophosphoranomethanide complexes

Synthesis, characterization and reactivity of a series of alkaline earth and rare earth iminophosphoranomethanide complexes

Communications Chemistry, Published online: 05 June 2025; doi:10.1038/s42004-025-01572-5Iminophosphoranomethanide ligands have been used to stabilize metal complexes, but their application as alkyl precursors in deprotonation reactions remains unexplored. Here, the authors prepare and characterize bis- and tris- methanide alkaline and rare earth complexes through protonolysis between dibenzyl metal precursors and the CH2(SiMe3)P(Ph)2 = NSiMe3 proligand or salt elimination reactions, and show that rare earth methanides can be used as synthetic precursors for the preparation of solvent-free complexes.

A computational investigation into the inductive effect in aliphatic and aromatic hydrocarbons has generated fresh evidence that alkyl groups are inductively electron-withdrawing relative to hydrogen and that this effect is small compared to other factors such as hyperconjugation.

Time to stop mentioning alkyl group inductive effects

New computational evidence reiterates that alkyl groups are inductively electron-withdrawing and that hyperconjugation dominates
