Herein, the synthesis and use of [11C]carbonyl difluoride for labeling heterocycles with [11C]carbonyl groups in high molar activity is described. A very mild single‐pass gas‐phase conversion of [11C]carbon monoxide into [11C]carbonyl difluoride over silver(II) fluoride provides easy access to this new synthon in robust quantitative yield for labeling a broad range of cyclic substrates, for example,...
Schnell und direkt: Die Carboxylierung von Boronsäureestern mit 11CO2 liefert [11C]Carbonsäuren als praktische Vorstufen für [11C]Ester und [11C]Amide (siehe Schema). Diese Umsetzung von Boronaten ist erfreulich tolerant gegenüber einer Vielzahl funktioneller Gruppen (z. B. Halogen, Nitro oder Carbonyl).
