Congratulations to Malini George on her defense! Very well done, #30 @WerzLab @UniFreiburg @FreiburgChem - the same is true for her research work on strained systems and expanded arenes. Thanks also to @DAAD_Germany for make this PhD possible.

Beautiful group 13 chemistry by Robert Kretschmer @KretschmerLab from Chemnitz @TUChemnitz in Freiburg @UniFreiburg @FreiburgChem @WerzLab @KrossingGroup @pappas_babis - and also besides chemistry in this @GDCh_aktuell talk it is always a pleasure to meet you.

@JbaraM90 My congratulation, Muhammad! Very well deserved.

I’m delighted to share that I’ve been promoted to Associate Professor with tenure! This would not been possible without the support of my amazing family &incredible colleagues, mentors, collaborators over the years, as well as the dedication of my exceptional students &postdocs!

Great finale of the lecture tour in Japan visiting Osaka and the Tobisu lab. Amazing 12 days are over! Thanks to all my hosts, especially Yoshiaki Nakao @KyotoU_News , for making this stay in Kyoto/Osaka possible. @WerzLab @UniFreiburg @FreiburgChem

@ducholab @KyotoU_News @UniFreiburg @FreiburgChem @Saar_Uni Thanks, Christian, looking forward to Monday.

@WerzLab @KyotoU_News @UniFreiburg @FreiburgChem Congratulations, Daniel! Very happy to see you next week @Saar_Uni!

Very happy to receive the IOCF Zen-ichi Yoshida Lectureship in Kyoto. @KyotoU_News Thanks to Michinori Suginome, Yoshiaki Nakao and colleagues! Always wonderful to be back in this great place @werzlab @UniFreiburg @FreiburgChem

@CChiGroup @KyotoU_News @UniFreiburg @FreiburgChem Thank you very much, Chunyan!

@WerzLab @KyotoU_News @UniFreiburg @FreiburgChem Congratulations, Daniel!

We @WerzLab @FreiburgChem @UniFreiburg just published dimerizations of BCBs in @ChemicalScience We think that this is very important paper for the progress of BCB chemistry since it elucidates background reactions to occur in the presence of Lewis acids. pubs.rsc.org/en/content/art…

It was a pleasure to be back in Tottori meeting former Seeberger @peterseeberger Group members Toshiki Nokami and Shinya Hanashima, being full professors there.

Kanazawa - a place not far from Kyoto, also known as “little Kyoto”, definitely worth to visit, also in terms of chemistry! Very warm welcome by Keiichi Hirano and his colleagues! Thanks a lot for your great hospitality! @werzlab @FreiburgChem @UniFreiburg

Osaka University: Wonderful start of my IOCF Zen-ichi Yoshida Lectureship. Thanks a lot, Koichi, for your great hospitality! @WerzLab @FreiburgChem @UniFreiburg @KyotoU_News

It was a pleasure to host @MarkGandelman @TechnionLive in Freiburg @UniFreiburg @FreiburgChem @WerzLab @pappas_babis and to learn about his unique chemistry based on nitrenium ions.

What a loss for the chemical community! I always appreciated his advice and our regular discussions during my time in Braunschweig.

@strained_rings @JOC_OL An important paper @werzlab @UniFreiburg @FreiburgChem for bicyclobutane chemistry demonstrating a new activation mode besides Lewis acid and photocatalysis @strained_rings Congrats to Jeremy and Daniil!

⚡🔋Electrochemical strain-release activation of bicyclo[1.1.0]butanes enables catalyst-free cycloadditions and arylations, forging oxabicyclohexanes and cyclobutanes—electrons as reagents to unlock high-strain C–C bonds @JOC_OL @WerzLab pubs.acs.org/doi/10.1021/ac…

Thanks Sigi Waldvogel for an enlightful talk about electricity in organic synthesis @UniFreiburg @FreiburgChem @werzlab @pappas_babis @TobiasSchnitzer

Unique chemistry of carbodications presented Florian Mulks @FFMulks from @RWTH at @UniFreiburg @FreiburgChem @werzlab @BBreitLab @pappas_babis @TobiasSchnitzer

@GavinCTsui Yes, I should. Would love to come back to Hong Kong. Already three years….

@WerzLab @UniFreiburg @FreiburgChem Daniel, next time stop by Hong Kong, high speed rail from Wuhan in a few hours only.

A fantastic lecture tour that comes to its end….thanks a lot to all of you who hosted me so wonderfully - in Wuhan, in Changsha, in Wuhu and in Chengdu. Special thanks to Liang-Qiu Lu for the initiative to bring me to China @WerzLab @UniFreiburg @FreiburgChem

@livesinchem This is so sad news! A giant of organic chemistry left us. I have so many good memories during my time in Göttingen.

🌻A great loss: Armin de Meijere passed away at age 86 on December 17 in Göttingen. Born in Duisburg, not too far away from the Netherlands, hence his Dutch name. His distinguished career spanned both the golden age of physical organic chemistry and the rise of transition-metal catalysis. De Meijere studied chemistry at the Universities of Freiburg @UniFreiburg and Göttingen, where he received his PhD in 1966 under Wolfgang Lüttke for spectroscopic and electron-diffraction studies. After a postdoc with Ken Wiberg at @Yale Univ., he embarked on his academic career: Habilitation (1971) and first professorship in Göttingen (1974) were followed by full professorships at the Univ. of Hamburg (1977–1989) before returning to Göttingen, where he remained until his retirement in 2006. De Meijere was famous for studies on highly strained polycyclic small-ring hydrocarbons, for developing new synthetic methods using cyclopropane and cyclopropene building blocks on the one hand and for transition metal—Pd in particular—catalyzed reactions on the other hand. He used such methods in the #TotalSynthesis of natural products and bioactive compounds. As early as 1976, his group reported a gold-catalyzed rearrangement, and soon after a photochemical trifluoromethylation—both notably ahead of their time. A plethora of fascinating three-membered ring-based molecules were synthesized, like polyrotanes and propellanes; acepentalene was first synthesized in his group, among many other achievements. De Meijere received numerous awards, including the Adolf von Bayer Medal of the GDCh @GDCh_aktuell. Around 250 PhD students and postdocs have lost an exceptional mentor—and chemistry has lost a giant.
