Super fun #Christmas night out with the group to celebrate a great year! Looking forward to see what 2026 brings! @unibe.ch 🎄🎅

We ended the week with a new #PhD in the group! Congratulations #DavidAnderson 🏴󠁧󠁢󠁳󠁣󠁴󠁿 on your PhD thesis advancing the #coordination and synthetic #applications of #organosodiumreagents @unibe.ch thanks @spthomasgroup.bsky.social and @albrecht-lab.bsky.social for being part of the examination committee

Always a pleasure to come back to my for the JCO2025 to represent the work we’ve done with @antorna.bsky.social since March in @unifr.bsky.social ! Happy to be part of this organic (and much more!) community !

Glad to see that my first paper in the Hevia group is out! This work would not be possible without the support from @antorna.bsky.social and @evaheviagroup.bsky.social as well as the DFT calculations from Ana and Manting!

Thrilled to share the work of @clarencetankl.bsky.social and @antorna.bsky.social on elevating #sodium mediated deprotonative #borylation to #catalytic regimes with an insightful #mechanistic study in collaboration with Max Garcia Melchor @pubs.acs.org @unibe.ch

Excited to see this work published!! Awesome work from Clarence @clarencetankl.bsky.social making catakytic borylation with sodium bases possible!!

As someone who studies autoimmunity "boosting your immune system" is how you get multiple sclerosis, diabetes or die as your immune cells slowly kill every other part of you in an orgy of violence. However, this list is a way to boost your immune system in a targeted way without incurring ANY risks!

Bonsoir !
Dans le cadre de mon projet postdoc à l’Université de Fribourg, je cherche un groupe disposant d’une GC préparative (ou semi-préparative) pour isoler et caractériser des monoterpènes (collaboration).
Si vous avez une piste ou un contact, je suis preneur ! Merci !

Today we participated in the unirun organized by @unifr.bsky.social during #Explora2025 ,the open doors days!! An excellent day, great weather and very good time with the people of the group! 🤗😊

Such a nice trophy 🏆 😁

Tienes 12, 13, 14 años.
Tu familia buscó un lugar que creían seguro y del que, hayas nacido en él o no -¿eso qué importa?-, tú eres parte.
Pero te cuesta sentirlo cuando ves cómo las bestias, cegadas de odio e ignorancia, atacan a quienes lo único que han hecho es tener tus rasgos y tus orígenes.

Absolutely magnificent lecture. Insight on how to properly apply computations to polar organometallics!

Very proud of our very own #LucaVedani flying the flag for @evaheviagroup.bsky.social #eucomc2025 presenting his work with @andryjborys.bsky.social assessing #biphenylene coordination to alkali-metal #nickelates @unibe.ch

Enjoying #pintofscience #Fribourg! Nice first night of science meeting the bars! Visit your local events and enjoy science :)

Magnesium Nickelate Complexes and Their Implications in Ni-Catalyzed Cross-Couplings of Aryl Fluorides and Aryl Ethers with Grignard Reagents The nickel-catalyzed Kumada–Tamao–Corriu cross-coupling reaction is widely used to form C–C bonds and receives continued interest due to the unique ability of nickel to activate challenging organic electrophiles containing C–F and C–O bonds. Recent studies on the nickel-catalyzed cross-coupling of Ar–F and Ar–OMe electrophiles with organolithium nucleophiles have unveiled the key involvement of highly reactive anionic nickelates, in which Li and Ni cooperatively promote the activation of these substrates. However, the possible formation of related heterobimetallic intermediates when employing organomagnesium nucleophiles as cross-coupling partners still remains widely underexplored. Filling this gap in the knowledge, we use air-stable Ni-tris(olefin), Ni(4-Me-stb)3 (where stb = stilbene), as a Ni(0) precursor to systematically investigate its reactivity toward several organomagnesium and organolithium reagents, which has allowed for the structural and spectroscopic characterization of a new family of nickelate complexes. Their possible implications and the influence of their constitution and speciation on the outcome of Kumada–Tamao–Corriu cross-couplings are also investigated through a series of stoichiometric and catalytic reactions, which have uncovered a dramatic solvent effect, hinting at the formation of contacted ion pair species as key to maximizing Mg (or Li)/Ni(0) cooperativity.

Very proud of this work led by Luca Vedani in Inorganic Chemistry @pubs.acs.org unveiling the role of low-valent magnesium nickelates in challenging "ligand-free" cross-coupling reactions!
