It is wonderful to hear that a long story has finally come to a positive conclusion. My warmest congratulations to Friederike.🎉

Synthesis, Structure, and 199Hg Chemical Shifts of Mercury 1,5,9‐trimesityldipyrromethene (MesDPM) Complexes DFT calculations for the Hg(I) 1,5,9-trimesityldipyrromethene complex, [(MesDPM)Hg]2, predict a 199Hg chemical shift of −648 ppm. The experimental 199Hg NMR spectrum features a singlet close to the p...

Super exciting chemistry, congratulations!

Functional Al/Cd Heterometallics─From Controlled Al(I) Transfer to Nucleophilic Transfer of Cadmium Ions Low-valent cadmium compounds have remained largely unexplored as electron reservoirs, with no precedent for their use in reduction or bond activation chemistry. Here, we address this gap by integratin...

Thrilled to share a first publication of the group! We report on cadmium aluminyls that find application as Cd-nucleophiles and(!) Al(I)-Transfer reagents. Now out in @jacs.acspublications.org ! 🥳👍
Thanks a lot to @chemieverband.bsky.social for the generous funding. pubs.acs.org/doi/10.1021/...

Until two weeks ago, I didn't even know this journal existed. And now I already have a publication there ;)
A wonderful collaboration with Manfred Scheer's group on a 13/15 analogue of ethene.

Vielen Dank an alle beteiligten für diese schöne Zusammenarbeit!

Transient Triplet Metallopnictinidenes M–Pn (M = PdII, PtII; Pn = P, As, Sb): Characterization and Dimerization Nitrenes (R–N) have been subject to a large body of experimental and theoretical studies. The fundamental reactivity of this important class of transient intermediates has been attributed to their electronic structures, particularly the accessibility of triplet vs singlet states. In contrast, electronic structure trends along the heavier pnictinidene analogues (R–Pn; Pn = P–Bi) are much less systematically explored. We here report the synthesis of a series of metallodipnictenes, {M–Pn═Pn–M} (M = PdII, PtII; Pn = P, As, Sb, Bi) and the characterization of the transient metallopnictinidene intermediates, {M–Pn} for Pn = P, As, Sb. Structural, spectroscopic, and computational analysis revealed spin triplet ground states for the metallopnictinidenes with characteristic electronic structure trends along the series. In comparison to the nitrene, the heavier pnictinidenes exhibit lower-lying ground state SOMOs and singlet excited states, thus suggesting increased electrophilic reactivity. Furthermore, the splitting of the triplet magnetic microstates is beyond the phosphinidenes {M–P} dominated by heavy pnictogen atom induced spin–orbit coupling.

Our paper on triplet pnictinidenes (P, As, Sb) with transition metal substituents is out; congrats to Marc, Nils, Tarek and Rich and thanks to all that have contributed to get a comprehensive electronic structure picture @haenisch-group.bsky.social
