Congratulations @k-eichhorn.bsky.social for being selected to this unique event.
Katharina Eichhorn@k-eichhorn.bsky.social · last mo.An amazing week at the 75th Lindau Nobel Laureate Meeting is over. I feel so honored to have been given this once in a lifetime opportunity. It was an inspiring meeting with interesting lectures, great conversations and wonderful scientists from all over the planet. I will never forget this week!
well done @k-eichhorn.bsky.social both in terms of cover artwork and the underlying chemistry
Katharina Eichhorn@k-eichhorn.bsky.social · 9mo agoExcited to see my very first cover artwork #OnTheCover of @chemcomm.rsc.org! It is a great honor to see my research highlighted in that way. Thanks a lot to @pchem.bsky.social for making it possible! And by the way I had a whole lot of fun by designing this! 😊
Congratulations from my side as well, it was my pleasure to be on the committee
Hering-Junghans Lab@hering-lab.bsky.social · 9mo agoWe present PhD No.4 from the group: Congrats Dr. Ayu!

Fresh out of the oven. Check out Chenyang’s most recent work in JACS (@jacs.acspublications.org). We explore the reactivity of a phosphinidene oxide as the electrophilic partner in Wittig transformations. Hope you enjoy. pubs.acs.org/doi/full/10....
A Fresh Twist on the Phospha-(Aza)-Wittig Reaction
The reactivity of an unsupported phosphinidene oxide, BnArNP═O (Bn = benzyl; Ar = bulky aryl group), as the electrophilic partner in Wittig reactions with ylides is described. Reactions with methylene-triphenylphosphorane (H2C═PPh3) and ethylidene-triphenyl-phosphorane (HMeC═PPh3), proceed as expected, giving rise to the phosphaalkene metathesis products and triphenylphosphine oxide. This reaction can be extended to other ylides such as N-(triphenylphosphoranylidene)methanamine (MeN═PPh3), to afford an aminoiminophosphane BnArNP═NMe. In these reactions the phosphinidene oxide plays the role of an electrophile, which would typically be the remit of an organic carbonyl in classical Wittig reactions. Further mechanistic insight into such transformations can be gained by altering the nature of the phosphorus-ylide. Upon reacting BnArNP═O with H2C═PMe3 (which possesses a smaller, more Lewis basic, phosphine) an alternative product is formed. This transformation supports the formation of a betaine intermediate that subsequently undergoes hydrogen-migration to afford an oxidized phosphorus(V) compound related to phosphorus acid.
