RESOLV member, Prof. Max M. Hansmann's research group has now been able to investigate the reactivity of C2O using an isolable equivalent in which the C2O is "masked".
The direct transfer of small fragments like "CCO" into organic molecules is highly relevant for organic synthesis planning and can significantly shorten synthetic routes. However, this approach is often limited by the selection of available reagents. Free dicarbon monoxide (C₂O) is highly reactive and unstable compared to carbon monoxide (CO), and therefore difficult to use in synthesis. Prof. Hansmann's research group has now been able to investigate the reactivity of C₂O using an isolable equivalent in which the C₂O is "masked." The current publication in Angewandte Chemie reports on the synthesis and reactivity of the previously unknown heterocumulene Ph₂S=C=C=O, which replicates the chemical reaction profile of C₂O in a controlled manner.
