ISOM 25, Liège, Belgium, 8-11 July 2025: an excellent conference with very inspiring talks. I spoke about the practicality of olefin metathesis using low-loading ruthenium catalysts. Thank you, Lionel, for the invitation. See you all at the next ISOM ♥! isom25.uliege.be

A very fine review “Sniffing Out the Sustainable Future: The Renewability Revolution in Fragrance Chemistry” by Dr. Franziska Elterlein, Dr. Nikolas Bugdahn, Dr. Philip Kraft. doi.org/10.1002/chem.2… I like the AmbreXolide™ part because of olefin metathesis!

“Studia naturalia impigro labore cultum et provectum non sordidi lucri causa nec ad vanam captandam gloriam, sed quo magis veritas propagetur et lux eius, qua salus humani generis continetur, clarius effulgeat” — Congratulations to Dr Łukasz Grzesiński for obtaining a PhD degree

25 May 1948 | Witold Pilecki was executed in Warsaw. A Polish soldier, a volunteer prisoner of the German #Auschwitz camp, a co-founder of the camp resistance. He escaped in April 1943 & wrote a report about the crimes in the camp. Our podcast: auschwitz.org/en/education/e…
Renaissance in Alkyne Semihydrogenation… What captivates me in this review is the idea behind the following conceptual diagrams, which show in great detail the properties of each discussed semireduction system. The idea is entirely @RafalKusy 's. 🧑🔬 doi.org/10.1021/acs.ch…

On 3 May each year, the Poles celebrate the anniversary of the 1791 constitution, the first such act in Europe and second in the world. Under communist rule, celebration of this holiday was forbidden.
Congratulations to Dr. @RafalKusy! Only his hard work and perseverance made this alkyne semihydrogenation review possible. It is huge—spanning 131 printed pages, it includes 289 high-res schemes and 731 references🔖 Use and enjoy! doi.org/10.1021/acs.ch… @IOC_PAS @ChemistryUW

Congratulations!
We’re excited to share our work that introduces singly N-protected O-vinylhydroxylamines as ring-annulation reagents for the synthesis of azaindolines and azaindoles. Congrats to Zach & Charlotte (@charlie_bird13) and the Enamine (@EnamineLtd) team! 🔗 chemrxiv.org/engage/chemrxi…
It was my great honor to chair the second day's morning session of the 5th Polish Inorganic Chemistry Forum #FChN. This morning, I had only the best speakers, including Bartosz Grzybowski @IOC_PAS, who gave the Professor Adam Bielański Memorial Lecture fchn5.pw.edu.pl
