The long-standing challenge of converting alkenes directly to alkynes—classically a harsh two-step halogenation/elimination—is solved by Ning Jiao & team! 🔗nature.com/articles/s4158… #OrganicChemistry #OrganicSynthesis #Alkyne #Nature #Chemistry

Is cyclic (alkyl)(amino)carbene a new N-heterocyclic carbene? “The development pathway of any catalyst family can be—through a somewhat stretched comparison—likened to the evolution of a family of aircraft. When analyzing the silhouettes and designs of major fighter aircraft from 1938 to 1942, significant similarities are readily apparent. All of them—whether the Spitfire with its mathematically elegant elliptical wings or the more angular designs of Professor Messerschmitt—were, with only a few exceptions, low-wing monoplanes with retractable landing gear and inline engines driving a propeller…” Read more about our view on the development of NHC and CAAC ruthenium olefin metathesis catalysts in our Opinion in Trends in Chemistry (link in a comment). #reviews #chemistry (Airplanes artwork © @GlobalPower123 FB profile)

🏆Congratulations to Dr. Łukasz Grzesiński—winner of the Prime Minister's Award for the outstanding PhD dissertation "Development of stereoretentive ruthenium catalysts through modification of chelating dianionic and carbene ligands." @UniWarszawski

With deep sorrow, I share that at the age of 91, my mentor Professor Mieczysław Mąkosza passed away. To me, he was more than a brilliant scientist—he was the embodiment of intellect and passion for discovery. Condolences to his family, friends and the entire chemistry community.
