Transition metal-free ketene formation from carbon monoxide through isolable ketenyl anions
Science, 2022, 378, 1331-1336; DOI: 10.1126/science.ade4563
Ketenes from ylides
Most chemical reactions that build complex molecules from carbon monoxide rely on transition metal catalysis. Jörges et al. found that carbon monoxide also reacts cleanly with potassium ylides by phosphine displacement. The resulting negatively charged ketenyl compounds could be isolated and crystallographically characterized, manifesting a bent structure poised for downstream reactivity at the carbon rather than oxygen site. This behavior was borne out in a variety of reactions of the anions with electrophiles to produce ketenes and their derivatives.
Viktoria was awarded the Klung-Wilhelmy Science Prize 2022 for work in the field of ylid chemistry and the development of new catalysts. Further information: https://www.klung-wilhelmy-wissenschafts-preis.de/
